I got five little plants was doing fine looking good when they was in my room under a small little bulb. I got my grow room up with a 1000 watt MH BULB on and now there drooping over. I don't know if I feed them too much or what. Do I have enough light on it, because my ballast was on 50% now I turn it up to 75%. Any suggestions on what might I be doing wrong?
