Am I behind schedule Day 20 (No Nutes) Autoflower

So I’m giving my Blue Lights a hair cut and then was considering giving her a flush already bc my runoff has been so low I was worried it would eventually lead to an issue and wanted to try and prevent that and now I’m seeing this on 3 or my big fan leaves that I kept specifically bc they’re lower to act as a warning sign before it got to my good stuff, and 1 of my new smaller leaves. I can only assume it’s because of my ph just kinda want to be sure. I skipped feeding last week so I plan on checking the ppms and feeding after if needed.

Sorry my camera is broken so this is the best I could get right now but it’s little rust looking splotches. I don’t see any type of bug or anything and my clawing from the possible Nitrogen toxicity is gone.

Looks like the beginning of a calcium deficiency to me.
Have I given you the semi-generic calcium deficiency screenshots yet?

No not yet you haven’t. Is it possible this is bc of my low ph? It’s been kind of low to begin with and this last time I fed I didn’t ph my stuff so I know my ph was low low and while I tried adding high ph when watering the runoff was still super low. I wish I could tell you just how low but I’m using test strips and the lowest it goes is 6.2, and it was reading 6.2 or lower before I added the non ph’d nutes.

Possible. Here are some vaguely disagreeing charts about pH and nutrient uptake (I think one of them confused magnesium for manganese, and they are in fact not interchangeable)

The important part is that they both agree calcium is best absorbed around the 6.3-6.8 marker. Lower than that and you may be seeing a result of the pH inhibiting calcium uptake. It won’t outright stop her from absorbing calcium, but she has to work much harder at it.


And here are some pretty good examples/verbal descriptions of Calcium deficiency.


Here’s a good “quick diagnosis” chart
Notably, it didn’t have calcium deficiency on it. So that’s odd.

PS, get a pH pen. :joy:

Thank you for those charts, for anyone potentially reading this that is a new grower I highly recommend creating a grow album and saving all of the stuff they give you into it so you don’t have to scroll and search for them pieces lol

Yeah my ph has been something I’ve been concerned with for a minute but hadn’t seen any issues and I kept the waterings high ph’d but I think the unchecked feeding is what did it. It makes sense as to why bud production is where it’s at bc it was on track to being faster than my Wedding Cake and all of a sudden there’s almost no more growth and the Wedding Cake is pulling ahead. Hoping I didn’t fluff it here this close to the end lol I’m mid flush right now so going to be at least getting the ph on track and then feeding with some Tiger Bloom which has some calcium in it as well as my tap water has some as well. I probably need to get some calcium additive though to quick start or no?

I knoooooow I need a pen lol I’m just broke asf :joy: although collectively I’ve spent as much on strips as I would a pen, it’s only an issue when it’s outside of my window on the strips :joy::joy::joy: one day I’ll finally get tired of buying strips and get a pen. Almost cracked and ordered a cheap pen but I figured at the very least the strips won’t go out on me in a potential few days :joy:

Cheapest pH pen you can get that’s still reliable:

Nah, not at all. Once you get the pH back in range she’ll level out and go back to eating. Just be sure to give her a couple days to respond to the changes. :v:

Amen to that. I started saving most of the common reference charts as Favorites in my photo album. So my Favorites looks like X-rated pics of my wife, and lots of weed diagrams. :rofl::joy:

And if that’s not the key to life I’m not sure what is :joy::joy:

So the thing I was wondering is if I lost valuable time? What I mean by this is will my buds grow to what the nutes/lights allow them to in a certain timeframe? Or is it almost a pre-determined size like genetics? Bc I know at a certain point your plant stops focusing on bud production and switches to trichomes I just don’t want o have wasted precious time if it’s literally only a certain window that it focuses.

Also on one of the pictures you sent it says that branches may become hollow and rot inside and while LST’ing I was try to push two branches away from each other close to the node and split it open a little, and it seemed kinda hollow in there and I didn’t know if that’s what it meant? It doesn’t look bad or concerning but reading that has me curious what exactly it meant.

For the split, you might want to “tape” it close.
If you have some Aloes, you can sterilize the wound and then close it with some kind of tape. It helps to prevent possible infection… I use Teflon tape, but any stretchy tape will do. If you don’t have Aloes you can use a bit of honey too. But if you use honey, keep your eyes open for ants… :nerd_face:

This would only happen with an extreme cal deficiency. I haven’t seen this happen, personally, and trust me when I say I abuse the bejeesus out of my plants. They see deficiency more often than a child in a third world country.

Nope! Hollow branches are sort of normal. They grow thick cell walls and reinforce almost like a straw. It’s if they become abnormally hollow (too thin to support their weight) or rot that I’d be worried about it.

Hi Aussie,

I’d like to know how often you use the teas and liquid seaweed per plant stage? As needed or with each water?

Thanks

With nutrient teas i use it twice in veg stage and the banana tea i use twice in flower stage and the seaweed liquid u can use that twice a week or once a week its up ro you i normally use it twice a week

Do you use any other nutrients in addition or just the teas and seaweed?

If im growing organics im top dressing with worm castings and kelp meal and alfalfa meal and fish bone meal and sea bird guano,but if im using coco coir with powdered nutrients i would water with a tea once a week and the rest of the week i would water with my nutrients like normal i hope this helps you

Yes that helps.

I have liquid seaweed and started off FFOF. 4 weeks in im thinking through the nutrients for after the initial wears off. I saw a guy only using liquid seaweed and water.

Small tent grow, AF.

I laughed entirely too hard at that so thanks for making me feel like shit :joy::joy:

I figured but that wa sky first glimpse inside so figured I’d double check! Thank you for the help!

Also just now realizing I didn’t flush properly. I didn’t water until it was the same as the water going in, I watered until the ph was good, which means there’s about a 1-1.5 difference in ph huh? Bc when I tested my feeding runoff it read low but I just contributed it it to the flush but I know realize I’m a little shturpid lol

Unfortunately I don’t have any tape but luckily it was both small enough of a split and the branches are sturdy enough that it’s actually closed unless you pry it so I added some honey to prevent any air getting in there which there’s this local couple that make their own honey and when I say it’s the best honey I’ve ever tasted like :drooling_face::drooling_face: they say it’s from multiple wildflower blossoms and it made sense after they told me because it was almost as if the more it sat on my tongue, it was like fireworks going off and I was getting little hints of different things and it just absolutely blew me away. But that’s what they’ve gotten so hopefully they enjoy it like I do. I want a bee farm so bad, and someone has apparently already made a “High Honey” by teaching the bees to use cannabis to pollenate and while I wanted to be the first it’s absolutely awesome to see others with similar ideas!

I know one person who uses milk and honey for his grow and thats all he gives his plants

I was wondering if you could use milk for calcium but then figured that the milk would probably cause your stuff to start sitting like if you leave milk out too long no?

My thoughts also, youd have to be positive you had the appropriate bacteria in your soil to combat that yeah?

I felt like a monster saying it but it’s so true.

There’s not anywhere near as much calcium in milk as we give credit to it for. A better use of milk is to make a lactobacilos culture and water with them. @Mark0427 has the details for doing it, I almost did but I never made it so he’s still my go-to.

I read that while trying to figure out if I could and I didn’t believe it for the simple fact of that’s what I immediately associate with milk. I’m going to have to give their thread a peek to see what’s crackin.

Also been curious if feeding habits can change the plant. Kinda like how if you eat before you go to bed it contributes to getting fat :joy: bc if so ya boi about to only feed right before sleepy time lol but from what I understand is that plants don’t store any type of nutrients or anything since over feeding just burns them.
