Maybe nutrient burn or?
My biggest plant has started looking a little sick, have a feeling it may be some type of nitrogen toxicity? Maybe it’s just got some nute burn? I have flushed it out and will leave it be for a few days and hopefully it perks back up

Hi 8th week of flower. Bottom leaves have turned yellow and died and yellowing is rapidly moving upwards. I think it's nitrogen deficiency so I've added more Biobizz Grow. Would be good to get an expert opinion! Thanks

Potassium deficiency?
Shes got about 2.5 weeks left, at first I thought the leaf discolouration was natural as harvest approaches but the necrosis has me worried. My guess is K deficiency. I was about to start flushing, will she make it to the finish line ok or should I attempt to fix this issue?

pH or root issue. Temp increase at same time.
Either pH or root issue ..? As plants recently had a growth spurt the temp in tent increased from 28 to 33, does this happen with plant growth? Nothing else changed.

Light green tops
I've got one plant with extra light green tops. Any suggestions or is this normal sometimes? See my diary for feeding details. I've treated all plants exactly the same the only difference would be the type of pot (airpot) and I didn't root prune like I did the others.
