I apologize about the pH. I have six other people that I’m helping and first thing in the morning I forget who is who. When using Advanced Nutrients you do not pH your water.
Since you’re using Fox farm trio you will pH your water after mixing
Your goal is to maintain 1000ppm in your runoff water. You mix your feed accordingly.
Let me give you an example. This is an example only
If you fed your plan by mixing a feed of fox farm trio, calcium magnesium, and your water and the total feed mixture was 700 PPM per gallon (feed going in) and your runoff measurement reads 900 PPm then you would add 50 PPm more on your next feed to see if it takes you to 1000 PPM runoff.
You’re simply playing with the numbers to get to whatever it takes to run off 1,000 PPm
Maintaining the perfect environment is most important as well.
Check with your manufacturers lighting recommendation for height and percentage of light
Make sure that your relative humidity and temperatures in your tent are up to par with your growth stage
Totally understand the PPM now. My light is sitting a good 16” above canopy. Now I have read that when you get into your third week of flowering you want the VPD to be around 1.3-1.4 is that for the rest of the flowering cycle or will I continue to increase VPD as I near the end. The question is now that we are past the first two weeks of flowering what should be my target VPD from here on out be? I was holding strictly 1.2 during VEG. I am at 1.36 right now.
First time grower. Growing outdoors. Growing Amnesia Haze auto flower.
I have a dumb question. I am using the Bergman’s plant food purchased through ILGM. Just started stage 3 (flower time fertilizer). The chart shows 1g per liter for week 1, 2, 3… etc…
I have been feeding them once a week (Typically on Sundays). But yesterday I had a thought, am I supposed to feed them the 1g each time I water (usually 3-4 times a week) or just once a week as I have been doing?
The plants look ok, one is tall and skinny and the other is smaller and more bushy.
I have started another plant seeding right now so if I’m needing to do something different, I’d like to do it with this plant.
It takes practice friend. All you’re doing is paying attention to the runoff and then dictate your feeding by the runoff results. You’ll get it.
My good man the most honest answer I can give you is “I don’t have a clue”. I don’t bother with any of that stuff. I set my light to the recommended manufacturing’s height during whatever grow phase I’m in and to their recommended percentage and I’ve never had a single problem whatsoever.
@Bentstick can you help this guy with his light VPD I know nothing about it.
Did you say you were in your third week of flower?
Pictures of your plant will help please.
Also to better assist what’s going on you’ll need the supply a lot more information
the type of soil you’re in?
what size pot you’re growing in?
are you growing indoors or outdoors? are you feeding to run off?
What were your last runoff numbers?
How old are you plants?
Do you have the proper tools to read ec ppm and pH?
Plants are 8 weeks old. The soil is ProMix & Top Soil. I have a PH reader. PH stays between 6.0-6.5. Sunlight is an issue due to neighbors. They receive around 6 hours of good sun a day. I water them until soil is wet.
First off I know you’re new. The type of help you need is pretty detailed. You’re committing a misdemeanor offense by hijacking @Q19Z6TC1 post so for further information and assistance you should start your own thread in the forum this will give you access to tons of members to get their assistance and opinions etc without potentially confusing @Q19Z6TC1 with tons of post on his page that don’t pertain to him/her.
I’m going to go ahead and answer your questions as I don’t think @Q19Z6TC1 will mind.
The first problem I see is you started your plants in peat pods from what I can tell and that’s going to create an issue later as the peat pods don’t disintegrate after transplanting the way they should. And your roots are going to smother the plant
The second problem that I see is your feeding. To answer your first question yes you should be feeding your plants every time you water them.
You need to maintain a runoff of 1,000 ppms to maintain a healthy plant. When you feed your plants I’m assuming you have a bunch of holes at the bottom of your pot for water to escape you’ll need to feed them additional water to get at least 15% runoff in some type of a catch tray when you feed them you then measure the ph and PPM of your runoff to dictate how much you feed on your next feeding.
The next problem I see is you’re not getting proper lighting to your plant. I have no idea what’s restricting you from getting full sun but you need more than 6 hours.
It’s in my opinion you’re going to need a lot of help to get you on track. I would start a new thread entitled something like help with feeding Autoflower outdoors
I’ll be honest you’re lucky. Your plants look relatively good but they’re headed for total destruction until you get on top of your issues. When things go bad they go bad fast!
Wish I could dont pay much attention to VPD as a stand alone, temps and humidity get insinc VPD will be in spec, by the shot of his/her controller raise humidity a bit,temp will fall a bit and things will be in awesome grow!
