This is Chronic Widow (Feminized, NOT Autoflower) in a 3x3x6 Tent and 3.9g AutoPots. Her light cycle is still 18/6 because I cannot get hear healthy enough to flip to flower. Her germination date was around march 10th
I am using Jacks 321 and pH’ing the water at 5.8
(3.8 part A, 3.1ish Part B(calcium i think?) and about 1.25ish Part C(magnesium, epsom i think?) per gallon.
I thought I was dealing with a calcium or magnesium deficiency, so those Part B and Part C doses have been boosted about 25% from Jack’s guidelines.
Grow medium is about 1-2 inches of clay pebbles and coc0 noir.
Welcome! Looks like they are hungry to me. Is this the first time you addressed the Calcium and Mag deficiency? I add 3-5 ml of Cal/Mag per gallon on off feed days. Some folks add it all the time. That might help if you just did that. Give it a day or two and see if it comes around.
I run auto pots as well and it gets difficult when 1 plant wants more or less than the others feeding from the same reservoir. What I did when I have one with an issue is I set her on top of the tray versus inside and I top feed her. Looks like she is needing more PK. Here’s few pics. Increasing part B and epson will only supply additional calcium, magnesium and sulfur. I would increase part A and top feed to run off. Results will take a few days to show and the effected leaves won’t recover or change
