Yellow leaves below and some others
Guys, I have this 6 week old baby with some yellow leaves and others (lower) completely yellow. What can it be? I have been using Biobizz Top-Max, Grow and Bloom in small doses as described in the diary. I looked in the deficit chart but couldn't find any answer by myself.

Day 20 Flower. Leaves curling
Leaves curled over 12 hour light cycle. Ph 6.0. Ppm 950. I have been battling ph drop for a week. Lowered Ppm to 900 from 1100. Seems to have stabilized the ph and now the leaves are doing this. I’m looking to do the day 21 strip of most leaves tomorrow. Should I be concerned?

Leaves are turning yellow from the bottom up and I'm not sure if it's the natural death of unessery lower leaves or a nitrogen deficiency. It's not a ph problem. Thoughts?

Burnt, should I throw it and start from zero?
I have 1 burn auto for excessive light, should I throw this one and start from seed again or maybe flipping to 12/12? The light is farther now but maybe I can do something else than put away my lights.. my current schedule is 18/6 and the plant is around 45-50 days old

Hey guys, I have noticed that some of the upper leaves are turning yellow. I read that it may be because of heat stress or light burn but I'm not entirely sure and just wanted to ask what i can do to stop other leaves from having this issue. Anyways, what do you guys think?
