Spraying yoru plants with plain water can leach nutrients out of the leaves. Make sure you're actually WATERIN"G your plants with a correct fertilizer, but be very careful since you're running a heavily pre-fertilized soil on young plants, which in and of itself can be a source of problems. Also, with LEDs, you'll have to make extra sure that you are not overfertilizing or overwatering, as compared to a hotter, brighter, HID lamp.
I'd lose the spray unless you find you actually NEED to foliar feed for some reason, which I don't see.
stinkyattic Reviewed by stinkyattic on . First timer, troubleshooting form filled out! I filled out this troubleshooting guide, I know this grow may seem a little ghetto, but i definitely have a budget and its just a test before we order genuine seeds...Our plants are green, but the lower leafs are drooping a lot and have yellowish spots on the leaves with some grey, but at the same time, the top half of the plant looks completely fine... I think i'm going to cut a exhaust and input port for two little computer fans and see if that will circulate some more air... Tell me what Rating: 5
