i got like a lil 6inch fan on top of them but im bout to move it n put it under them. im still havin my bottom smaller leaves turn light green wit lil brown circles that look like burns. u think this could be the fan? the temp? lack of nuts? i also have a black blankit covering my set up so it traps the light and i havent checked ph at all. goin to hydro shop tomorrow to get ph test kit for water n a ph reader for soil some mylar n some veg nuts. let me know if anybody got any suggestions on what i should do?
