so i'm into my first grow ever. my plants were veggin for 6 weeks, then flipped to flower, for 2 weeks now. they're ranging like 4 to 5 ft tall, looking good. right when i flipped them, i took 24 clones. they're all still alive, and have had new growth, and growing after the first couple days. it's been 2 weeks now, and there's no roots showing still under the rockwool? i know it can take up to 3 weeks to see roots, but isn't the growth suppose to come after you see roots?
