GSC Auto Day 56 Possible Deficiency





Should I be concerned about the yellowing on the edges on some of the lower leaves and tips of some of the upper leaves? I am using foxfarm ocean forest soil mixed with perlite, the 3 stage foxfarm grow nutes and cal-mag at the recommended feeding scheule ratio. I have recently been watering her with half a gallon every 3-4 days (whenever dry) and I only use nutrients every other watering. I always ph the dechlorinated tap water to around 6.0. I’m still on the veg cycle for my tent setup and have not started bloom nutes yet since I’m hoping to veg for a little longer. I plan on pruning away some of the bottom leaves that are more damaged before the next watering. Any thoughts on if I’m doing the right thing? I bought the foxfarm flush nute bottle and I’m contemplating if I should flush her before I switch the light cycle, or if that would do more harm that good.

This resembles a PH issue. The FF line of nutrients is salt heavy Growmie and recommend feeding to 30% run off on feed days and checking the PH and PPMs from the run off. Without run off those salts will accumulate in the root zone and tank your PH. On your next feed day going with just water at a PH of 6.5 to liberal run off and check the PH and PPMs. 6.3-6.8 would be the PH range and 800-1200 for the PPMs in soil :love_you_gesture:

I just ordered a new pot stand that drains into a removable collection tray and a digital ppm/ph meter so I’ll be able to do those tests. The self watering stand I have her on seems pretty useless for the style of grow I’m doing since the roots would need to extend and penetrate all the way through the bottom of the grow bag. I didn’t really read up on how they worked before I bought them but it’s my first try so there’s a lot to learn

I’ve just been using the liquid ph adjuster bottles with the test test indicator solution so far so I haven’t been keeping track of a lot of numbers

Your in good hands but I’m curious about your light cycle if they are autos they will flower when they are ready regardless of your light schedule. I grow with 18/6 for light schedule entire grow.

That’s interesting, I’ve read about people doing the longer light schedule throughout, some people even do 24hr the whole time with autos. I’ve just noticed her leaves look pretty tired towards the end of the nights so she might want the shorter light period, but maybe it wouldn’t matter. The seed said it was an auto but its taken a long time to flower so I’m thinking that changing the schedule could speed up the process.

Can’t hurt and I believe they do need some rest from light. I grew this super skunk last grow on 18/6 it was a auto

@OGIncognito thank you for the tag. Is it that obvious with me in numbers :astonished:

Hi @GoochsGanja
@OGIncognito has tag me to try to assist you in getting on the right path with your girl. Please correct me on anything I may be stating that’s not correct.

You have one single Auto flower that you’re growing you’re still in veg. You’re feeding Fox farm trio and you’re utilizing the soil feeding chart to do so.

It also seems correct me if I’m wrong that you’re using full strength of what they recommend you to feed?

I also understand that you do not have a pH and ppm pen but you have ordered one correct!

If it wouldn’t be too much problem could you send me a link to the pen that you ordered or a picture of the pen that you ordered

From the looks of your plant and the stage of growth in veg that it is in utilizing a half gallon of water is not proper watering/feeding habit for this stage.

At this point. Until you get your ph/ppm pen in you’re going to have to wing it.

Rest assure all the problems that you have will be addressed properly and your plant will return to 100% healthy and happy.

Exactly how many weeks into veg are you?

What size pot are you growing in?

Lots of learning curves with this hobby Growmie. Took me about 3 runs to realize the importance of PH, nutrients, lighting and the environmental conditions. Once I got those dialed in it’s pretty much hands off and let them do their thing :love_you_gesture:

I see you’re in a tent and you’re using a net.

Also I noticed you made a statement that you’re utilizing bottom feed Auto water feed trays and they’re not working properly.

You also stated that you have purchased some new stands that have collection water trays so you will I’m assuming be switching over to feeding/watering from the top. That’s a very smart decision and I highly suggest that you do this.

I also noticed that you’re utilizing pH strips to test your water and that will be okay until your test meter comes in.

Do you have a bottle of pH up mph down to adjust your pH levels? If you don’t you’ll need to get some as soon as possible.

You’re growing an autoflower. It’s a very unique plant. They’re very simple to grow. However, patience is the number one thing you need with an autoflower. When we make a mistake with an autoflower it could result and devastating damage. Autoflowers are very sensitive and don’t do well in the healing department as they’re on a clock.

You don’t need to adjust your lighting schedule it’s not going to do anything to speed up the process of your plant flowering. When your plant is ready to flower she’ll flower. As @John7 said. Keep your lights on 18/6

You’re 56 days old on the plant. When did you transplant them into the pot you’re in now?

Did you plant the seed in a Solo cup and transplant into your final pot or did you start the feed in the final pot?

I’m sorry to ask a lot of questions but the more I know the better I can help

Thanks for looking into this for me. Yes I am using the full strength of the recommended feeding schedule. It’s per gallon on the feeding chart so I’ve been doing half that amount to keep it proportional.


Here is a link to the ph and ppm meter I ordered: UIUZMAR Digital pH Meter pH TDS EC Meter for Hydroponic Nutrient Solution pH and EC Meter with LCD Display TDS Water Tester pH PPM Meter for DWC Setup Aeroponic Growing Tent Indoor Plant Grow: Amazon.com: Industrial & Scientific
It’s already going to be here overnight. However the new stands wont be in until Wednesday.
How much water would you recommend for next watering? Last watering I used nutes so this next one I’m planning on just water.

As far as how many weeks into veg I am I’m not exactly sure. I started in a small square pot in a germination kit, then transplanted into a 5 gallon fabric pot when she was day 18 from sprouting from the soil.


Then on day 24 I started LST

This was progress by day 32

And by 40 it was looking like this

So I’d say I’m somewhere between 4-6 weeks into veg.

Even though I have the self watering stands I’ve never actually put water in the bottom since the roots don’t extend that far down, so I have been watering from the top from the whole grow. I still plan to get rid of them and am getting the stands to promote drainage.

I don’t have any test strips for ph, I’ve been using a liquid testing solution I mix 4 drops of with a little water and check color to test. I do have the ph up and down solutions and have been using them to get the water down to a ph around 6.

If you think 18/6 for the remainder of the grow is best I can try that.

I think that should answer/clarify any questions you had, lmk if you need any other information

Forgot to mention I also sprinkled great white on the root ball and mykos in the hole during transplant.

Thanks for getting back the answers to my questions.

I start veg the minute I transplant so I’ll agree with you you’re in week 6 of veg. Typically you would have already seen pre-flower stage appear by this time on a normal autoflower. However, in my last grow I had a green crack auto that took 12 weeks in bed before she flowered.

You’ll continue to simply use your feed chart in week 4 until you see pistols coming out of your bud signs (white hairs)

Please send me the link or a picture of this runoff catcher stand that you have ordered

As for now, you’re going to discontinue feeding until we get a liberal runoff of 20 to 30% so we can see how much nutrients are in the soil. And what the pH of the soil is.

I’m not against the scrog net you’re using but it’s going to create a serious obstacle for you feeding and catching runoff. Thank God you only have one plant. When you water your plant should do it evenly and very slowly so that every drop of soil gets water how you’re going to do that it’s not going to be easy with that net there. I use the 2gal pump sprayer and take the nozzle tip off that gives a nice slow even watering.

You asked, how much water should I be giving the plant?
You’re in a 5 gallon bag. I would say that utilizing your feed/watering will take 1-1/2 gallons of water every time you feed to get a 20% runoff in your catch tray. This means you’re going to get approximately 4 to 6 cups of runoff every time you water. You keep that run off and measure the PPM and the pH every time.

I strongly suggest you printing out a monthly calendar and simply documenting your feeds going in and your runoff numbers going out. This will give you a record that is very valuable to have for future grows.

The way I catch my run off water is I simply use these Coke or Pepsi crates turned upside down on top of a dollar store turkey pan Just to give you an idea.

As @OGIncognito stated above you’re using Fox farm nutrients which contain a lot of salt. It’s very important to get the runoff for both documenting your numbers and running off the Salt from The Roots. Salt build up in the root zone will create issues in your soil and the proper uptake of nutrients to your plant.

Making sure your plant has a sufficient dry time is very important as your plant needs oxygen and can’t get it when your plant is constantly saturated. It seems as if you know when your plant is dry and ready to eat/water.

As you know your Fox farm soil comes precharged with nutrients to help get your plant through the first 30 days or so without having to feed any nutrients. I’m fairly confident since you have not been giving any runoff and only feeding a half of a gallon of water each time that your soil is seriously built up with salty nutrients still in your soil. So once again we’re going to discontinue any food (nutrients) until we get your first runoff numbers.

I don’t want to blow you up with too much information that one time so we’ll take it step by step.

Should you not receive your ph/ppm meter before your next do watering I want you to up the watering too 3/4 of a gallon of your tap water Ph it to 6.5 (let me know when your meter comes in)

The next thing that I have not seen mentioned in this post is your environment. The environment in which your plant is in is most important to maintain certain parameters to assure a happy healthy grow.

Do you have a dehumidifier?
Do you have a humidifier?
Do you have air conditioning?
What is the current temperature in your tent during the day?
What is the relative humidity in your tent during the day?
Do you have an exhaust vent in your tent?
Do you have fans blowing air around in your tent?
What type of lighting do you have?

If possible take some pictures of your tent inside so I can see the environment.

That should be enough for now LOL

If possible can you provide me with a list of all the nutrients and additives that you have available for your grow at this time.

Also it’s very hard to tell pistols (white hair) from New growth. They look so much alike. However, based on this picture from above it looks as if that possibly could be some pre-flower pistols

I do not have a dehumidifier.
I do have a humidifier and I have it set to keep the tent at 60% humidity.
I have an a/c inline fan on the top of the tent blowing air out a duct.
I try to keep my temperature around 70, it has been between 66 and 76 consistently because I have a full ac infinity smart setup.
The humidity is kept at an average of 60 rh and fluctuates from 58 to around 78 right after the humidifier is turns off, but then the fan brings it back down quickly.
The inline fan exhausts out the top right of the tent.
I have a rotating clip fan in the tent blowing on the plant.
I have the ac infinity samsung led grow lights, 2x4 size, 2x4 tent.

A lot of the conditions for this grow were not originally intended. It started off as more of an experiment but as I have been seeing more and more success I have been wanting to take it more seriously. I was planning on doing 2 or 3 plants but only one seed survived seedling so I have done my best to optimize for growing one plant in a wide tent using the scrog technique.

The nutrients I have available are
-FoxFarm Big Bloom
-FoxFarm Grow Big
-FoxFarm Tiger Bloom
-FoxFarm BushDoctor Cal-Mag
-FoxFarm BushDoctor Sledgehammer
-Great White
-Mykos

The photos I provided didn’t have a very good shot of the pistils. This one is a bit better angle, I could get better ones once the lights come back on.


I can definitely see pistils forming at the base of the nodes and on the new growths.

I believe you can keep your environment pretty dialed in. I was expecting to see a lot worse because of summertime but you seem to be okay.

Looks like you have everything you should have for the tent.

Your problems a very simple to fix. The majority will simply adjusting your feed cleaning up your soil and establishing a better microbial life.

One thing that I see that if it were me I would have some type of microbial life additive and in microbial feed. Your soil already has some but keeping it alive and adding additional is another thing.

You only have one plant but if you consider doing this in the future I would invest in a few more additives that will give you the microbial fungi life and something to feed them with. I’d be happy to suggest excellent products to you in that category should you need.

Keep me posted when you are meter comes in
