flowering

So this is my first grow, however i've had some professional help. everything was going perfectly until a couple weeks ago when i noticed some powdery mildew. I would sit in my grow room, taking my time with my ipod plugged in to the speakers i have, and carefully remove affected leaves...

dammit all the hell i wrote this and acc closed the browser window aghh i hate myself right now ok i have two plants one small one taller taller on has broader leaves lighter color shorter one darker color longer skinny leaves i think i may have a sea of green plant seed witht he shorter...

Hey all, newbie here, I was wondering if someone could tell me is it better to use bonemeal or bloodmeal during the veg stage, and then flowering. How much of a variance can I have in my light cycle. If im off half hour or so in either direction, are there if any adverse effects? Thanks for any...
