Defoliation… once I removed some fan leaves, I noticed some discoloration in a few leaves and a bit of powdery mildew starting on a couple of the lower leaves. I’ll apply Lost Coast to everything in the tent when the dark cycle starts and bump up the exhaust fan to reduce the humidity.
What’s causing the leaf tips to curl? I moved the light away and reduced the power to 75%. Please advise on how I can address this. Looks like her growth has changed, a bit slower and a bit lengthy.
look like light burn and to much humidity
for light will be better if u download PPFD Meter and try fix your light height also PPFD for flowering stage is 800-1 000
The ideal cannabis flowering humidity is between 40% to 60% keep it around 50% will be perfect
late flowering 1-2 weeks before harvest bring down humidity levels as much as you can 30-40%
