Hey guys, new here. I've got problems.

Well I'm growing GDP and mazaar i-shariff in the same system (dumb i know). The plants in the picture are GDP, the leaf cupping has been going on for almost 1.4 weeks now. I was told it could be over nitrogen, so i've been cutting back from adding nitrogen to the rez when i need to add more water and nutrients. As well about 3 days ago i took out about 6 gallons of water and replaced it with new R/0 water and added nutes with less micro and more bloom. they seem to be using about 3 gallons a day and i feed them 2-3 times a day, though i'm afraid i'm still overwatering even at that. Some show it worse then others but they all have it. The new growth seems to exhibit it alot near the middle and bottom of the plantand so does the bigger fan leaves all over.

The mazar's leaves seem to be thin and and not very firm, though they arent wilting. I was thinking this could also be a nitrogen overdose. The mazars are much bigger than the GDP.

What do you guys think, if its not nitrogen what stressing elements could i be concocting here?

The pictures are of three different GDP plants. Yes there is a bit of a pm problem going on that i'm trying to stay on top of. Baking soda helps a bit but not that much with my humidity. Going to get a de-humidifier. If anyone has some good ideas as to what spray is the best to get for PM i would appreciate it as well.

THANKS TO YOU! imp:
