Hello, Pistil is turning brown I think is too early for that, and also I lower the light power I thought maybe they get burned am not sure so I will need some help, is this a light burn or something else?
Anything from
Wind damage
Wrong RH, or swings of it
Nutrition burn ( overdose)
Wrong ph
POLLINATION
Low temps
Light burn
Think its most popular in all cases except POLLINATION and nute burn not a biggie, just esthetic...
