New grow - Need help!

[McDanger]

Plants are mature enough to flower when the nodes are alternating instead of in pairs. I think you may be able to sex them now but I couldn't tell from the pics. Look where the node meets the main stem (pic). I would only feed every 3rd watering and only water when DRY (pot will be pretty light).Don't use bloom food until flowering.

Well, its been awhile since i last updated. I've been so busy lately, I haven't had time to post. My girls are moving along quite well, I think. That being said, I'm pretty sure they're girls. I know for sure two are, but the 3rd is kind of unknown at this point still to me. I chalk that up to lack of experience in knowing what I'm looking at. I just started flowering this week. I think I waited a lot longer than I needed to or really should have. I hope it doesn't screw up things that I waited to start flowering so long. Its been roughly 3 months of vegging. They look huge to me, but then again, I'm fairly new to this. Any thoughts on how they look or if people can spot any problems?

I haven't added any more lights yet. I wasn't sure if more are needed. I know obviously more is better but I'm running out of room for my lights since they've grown so big. My lights are just about as high up as they will go unless I re-configure how they hang. I appreciate any comments and with them just starting the flowering, I expect more updates.
