My new plan now that I'm on 12/12 is to water the plants at/near the beginning of the 12 hours of light. Is there any pro's/con's to watering at certain times when there is light or when there is no light? I'd like to leave the plants undisturbed throughout the 12 hours of darkness, hence watering them at the beginning of their light period. Also, I'm watering the first few days with normal water, and switching to bloom here in a few days. Do watering trends change during the flowering period (due to growth, etc..)?

thanks again, this has been a fun and successful first grow for me, mostly thanks to this website and those who've helped - you know who you are!
