Can someone confirm if this is indeed light burn? im using an SF-1000 lamp but can't seem to find a distance/intensity chart. it's currently 55cm from the top of the plant at 80% intensity

Servus Mate, Slightly yes...i'd go down to 70% and check the new shoots for bleached tips. Good luck for the rest of the way..

I would say nutrient burn, not light burn. Seedlings 24 inches Veg growth 18-24 inches Flowering 12-18 inches. I have only ever grown at 100% intensity.
