umm yer best bet is to stop watering so much and move that light up more...its too close....short and fat is nice but they will do better....the spots look like where wate sat on the leaf and the light magnified it burning yer leaves...also looks like spider mites.....the foil is kinda useless and u need rais the light.....and she is old enough to live without the fertilizer.....ur soil looks good....water every 3 weeks and raise the light so its about 6-8 inches above her....have fun smoking that finished produect...its gonna be nice!
