m0useanswered grow question 2 years ago To the best of my understanding, the average reasons why leaves would die off in week 6 or 7 would not have to do with contagions in terms of disease. I would like to assume you have pests under control at this point, however the dying of the leaves maybe replaceable in other plants based off my theoretical estimation that it is caused by user error in the substrate, be it PH or nutrient in nature.
Honestly though there is not enough information here to answer your question, no diary linked or photos. So anything anyone says is garbage.
Leaves dying off could be any of the following:
nutrient burn/deficiencies?
disease?
pests?
heat stress?
PH issues?
high/low salts?
RH issues?
Also to phrase it as a hypothetical is not logical.
It either is or is not happening.
Best of luck
