How much bud do you think is expected from both of these plants if I were to start flowering this right now under a 400 watt hps.
First, you're feeding too much nitrogen. That's why your leaves are dark green and curling/clawing. A 400 watt isn't going to be able to penetrate 4 feet down, so really only the top 2 ft are going to grow decent buds. Your plants will most likely double in height when you put them into flower.
Thanks for the great news !!!!! But the leaves are actually curling from being too close to the light . But the darkness your probably right about.
