ok so i am trying my hand at hydroponics. Picked up a producer for about 1/4 of the price . anyways, i have gotten the plants to germinate nad they all have preflower leaves. sorry no pics but a couple of questions. since they are not on the automatic feed yet, about how many times a day should i be watering them? (they are in rockwool) and what nut strength should they be on? currently i have been watering every other day (i know prolly real bad to do) and the strength is around 300 ppm. im following the directions on the back of the sensi nute bottle, but somehow i think im doing something wrong seeing how its been a week and they really havent grown at all. they look nice and green color, but not really growing.. little help?
