Hows everyone today, I have a pineapple express that has a upper leaf problem that I could use some help with. Bio thrive nutes, 6ml calmag, 6ml bloom, and 3ml bio bud, ph at 5.8 morning feeding and 5.65-5.7 evening feeding, temps 82-83 lights on, 69-70 lights off, humidity 35-45%, Grown in coco. I have seven in flower all at about 21 days since flowers showed. This is only one with problem. Could it be light burn, I grow with led and the light was about 14" above canopy, raised to 18" or possibly Iron def.
The tip burn is from 2 weeks ago when I switched to flower nutes.
