answered grow question 5y ago
Hi I'm only seeing it on the upper leaf? So its an excess it's very early on. Otherwise I might lean more towards a heat or light stressed plant..especially if you're only seeing high up on the plant, leaves directly in the light.

What's causing my brown crispy leaves!?
Over the past week my plants have taken a turn for the worse. Many leaves went from yellowing to browning to completely crispy! Other leaves have brown spots on them and some of the stems are purple.

Day 43 vegetative. Problems have occur since week 2. I already remove the first biggest set of fan leave at bottom. Problem slowing down but still happenin
The problem slow down after I cut dying leave on the 2-3 week and water it with nutes. But it is still creeping on fan leave. Only on fan leave that grow from the main stem. I always check my water and soil ph and everything is around 6.4-6.8ph.

Late flower issues- chop early?
Week 8 of flower (haven't been best at keeping up with diary). Poor girl is deteriorating rapidly but I don't know why. Too late to fix, but too early for ideal harvest. Should I just let her ride or chop early and try to salvage what I can?

45 days flowering yellowing
45 days of flowering, is it a bad yellowing or it's normal for this phase? Always did 1ml/L of biogrow, I think I'll put 2ml/L till flush. It's nitrogen, right?
