Hi there,
This is not my first grow however it is my first flood and drain grow. My plants are 55 days from cutting and 21 days into flower. My nutes are FF and today they are adjusted to 1270 ppm with a ph of 5.8. They seem to be very content. Today I noticed this on one of the fan leaves. It seems to be drying out and cracking. I can't seem to find any pests. Oh I should add that the res is kept at 66 deg. f and the ambient temps run about 85 deg. f.
Hey any ideas or suggestions would be greatly appreciated.
