Starting to yellow
So I had good growth up until 2 days ago when the one plant started to yellow. I had them going 24 hours a day and I got grow dots mixed in the bottom two thirds of the pots. Could this be light stress? or could it be hungry?

I keep loosing leaves to some sort of nasty necrosis. It affects leaves at all levels, small and big randomly. I had to remove a lot of dying foliage
At first it looks like a asymmetrical spot of leaf starting to thin out to lighter color then tissue dries and turn black. I have high runoff EC3.3 and I blame Easy boost pellets because I only add rootjuice 1ml/L and sugar royal 0.5ml/L to my water. What is it and how I fix it?

Could someone please explain the precise mechanism underlying the phosphorus anomaly? As anticipated, availability decreases with increasing pH, yet it exhibits a sudden surge at pH 8.5. What is the exact (bio)chemical rationale behind this phenomenon? Boron has a similar pattern

Nitrogen deficiency or could it be nothing
In the pictures you see some yellowing and small spots. I don't know if it's Nitrogen deficiency or not because it stays with those two leafs.

2 autos with crispy feeling sad looking leaves, how can I help them? (more info in diary pl & crit)
2 of my autos have been growing leaves that feel crispy and look deformed. I have been watering when the top 5 cm of the soil dries, but I fear maybe I fed them too much nutrients. The temp has also been on the high side (30C 80F). What could be wrong and what can I do for them?
