karn888 Day 16 (Week 3) - some leafs show some yellow spot. Only happens with this one (other plants are doing fine with the condition)
Day 21 (End of Week 3) - Defoliate & LST. Installed humidifier and spray onto leafs
It's because your temps are high, maybe your light is too powerful or too close. Maybe the humidity isn't as high as you think. I would try to bring the temps down as a raise humidity. Spray the leaves daily with water, should help.
