Trying to figure out how to get pics in here. Was wondering if anyone could help me in diagnosing my plant problems. I'm thinking maybe on one of the pictures where there is brown on the edges maybe nute burn and the other looks like a possible mag deficiency but I'm a very newb grower so I thought I would ask some pros. My system is a rdwc nutes are heavy 16 at 600 ppm temps are at about 80. Lights are topledgrowlight reflector 144x3 series. Lights are about 12 inches from tips. 3 weeks into flower. Water temp is about 75. Well water is filtered to about 80 ppm. If any additional info is needed I will happily give it.
