Hello all
I have noticed this problem recently(pic) wrinkled leaves and missing parts of leaves. hese are 5 days into flower and was just looking for some ideas as to what the problem may be. I did switch from mh to hps,and changed the nutes slightly to tiger bloom (dwc ppm 1540) I did have this problem before changing nutes. Any help would be great:)
