Rockmachine under Viparspectra P1000

Hello guyz, It's been a difficult week for the ladies in the tent. I'm not sure what I was doing wrong this time but all of them except from one plant suddenly showed some kind of deficiency as leaves started to curl down as they were over watered which was very strange as I've been sticking to the same watering technique for quite long time :( I started looking for the possible reason and came to the conclusions there might be two scenarios: - too much nutrients: tips of the leaves showed slight signs - the light intesity is to high So I flushed the twice with tap water with controlled pH to 5.8 The situation hasn't changed for few days which gave me huge worries. Yesterday I performed quite an aggressive defoliation and flushed them again, this time with low dosage of nutrients (around 1.0 PPM) They totally recovered and are already looking healthy today. Unfortunately one plant started producing male pollens at the lower side of the plant and I'm not sure how to continue now. I immediately removed problematic spots but I would really appreciate your help on how to proceed. Should I leave affected plant int the tent? Looking forward for better times in the following week. Last but not least thanks for stopping by and all the likes & comments! See you around folks! :))
