Lights are now on 12/12 schedule
I did a major defoliation on the same day I switched the light schedule.
I also reduced PPM this week to avoid nutrient burn/stress since I turned on IR and UV.
@Ferenc, at the begging my little got burned because of the light and too much water on the dome (light reflexion?). My plant looks awesome now! I just started my account (didn't know about this website before!), updating my diary here. Last ~2/3 weeks to harvest from now! :)
