Everything was looking amazing, then I went in there yesterday and they looked like this... I do not know if it was a deficiency or nutrient burn, so I flushed the Coco mix two nights ago and gave it 50% strength nutrients tonight. Has anyone seen this before, or have anything happen this rapidly?
Yes, extractor fan and oscillating fans are working. Temps are 75 with lights on and 60-70 with lights off. It's definitely not light bleaching.
