Looks like potassium to me. Do not raise your nitrogen level in process. Your well fed there. Always be aware of run off ph and tds or ec.

Bottom leaves yellowish - why? And can I top?On both of my plants (C99 & S.A.D.) the bottom leaves are turning yellowish and I can't figure out why. I'd also like to top them this week (above 3rd node), but I'm hesitant because of the leaves. Any advice on what they may be missing, and whether I should wait with topping?Leaves. Color - Yellow

Week 2: One of the plants still doesn't look good + other beginner questions :)Second week and one of the plants has weird spots + leaves curled.
Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea.
Also, when should I start feeding the plants?
And how much water do I need at this point? 😥9 months ago

Brown spots on top leaves - nutrients, light or something else?She went into flower, now stretching. Set light to 100%, added Bio-Bizz Top-Max and Bio-Bloom (1ml/L each).
3 days later brown spots appeared on top fan leaves, very few also on lower fan leaves.
I suspect this could be light burn or nutrient related.
Any ideas? Pls help9 months ago

Nitrogen deficit?The bigger plant is struggeling a bit again. After some talks and readings it could be a nitrogen deficit but am not really sure how if I should react to it, since the need of the plant should get less for nitrogen in the next weeks. Please read my journal for more information.Week 7

So I noticed on day 6 she started to stretch, she was the leggiest out of all 4. I swapped out the cup as it had a surround on it for jug to improve light.
I think this has helped.
BUT her cotyledons are very dark green and curling down and under, and her top is smaller+darker??Leaves. Tips - Thick
