Is that tinfoil? Possibly hot spots. Hold your hand on top of the plants for a min or so. If your hand gets hot, raise the lights up.

It looks similiar to light burn or Overfertilization, what type of lighting are you using? Also, you did mention your rh was 30% that seems low should raise it. Flowering plants grow best in a relative humidity range from 55%to 60%. Happy growing:peace:

you want low humidity in flowering actually, it increases resin production and makes molds and fungus a much smaller threat. Bud mold really sucks.

30 % is too low if your worried about fungus at 50% then get some air movement . i think light burn is the anwser

Sometimes it is so hard to tell by pictures, etc. And everyone grows different ways, I have learned from years of experience, other growers, trial and error. And each room is different. I have two flowering rooms, one largerw/CO2 Burner everythings on a top of the line controller....so I can program and check it regularly.The smaller one isn't and it works great too, But it's inclosed envirment is optimal for the type of strains I grow. I suggest to everyone "Marijuana Horticulture (The indoor/outdoor) Medical Grower's Bible
By Jorge Cervantes...I read it over and over. And one is Garden Saver, www.quicktrading.com, I have met the author Ed Rosenthal Personally and is the man! They have helped me and save alot of grows! Gooluck and hope you get enough infro to help.:leaf:
