i am not sure what stage you are in with the grow - but to me it might be needing a twice feed in the week - as it does like natural drying -- but its only my opinion - i did have a couple that did this about the end of the grow about 2 weeks before actual harvest - even one about 15 days into flower
again its only my opinion from what i dealt with personally but got no pictures just cut the bad and moved on -- other than that it looks very nice hope it turns out for you
Im pretty shure it is nutrient burn but it is kind of weird because on my 3 plant she is the only one to do that and im using the same mixed water for all of those so I dont understand
What growing medium is it in? Also, what have you been feeding it for nutrients?
I think I find the problem i measure the humidity level in my plant and i realise that is not because the top is dry that the bottom is so I th i was just feeding her to much but my meter measure humidity and ph but it is a cheap can you give me a idea of a good brand that made that kind of product but with good precision
Flush that baby. I would back off the nutrients for bit
