Veg day 20, 600w hps. How am I doing?

Hey folks, first grow here. Vegging under 600w hps right now, 1200w for flower. Heres the rundown on the setup.

• 4x8x6 foot tent.
• 2 600w magnetic ballasts
• 2 cool hoods
• Dyna Gro nutes (Protekt, Grow, Bloom), also General Hydro ph up and down.
• FFOF
• 2 Purple Kush, 1 G13

I've lst'd one purple kush and the g13. Here are some pics. Any tips, criticism, and comments are welcome. (sorry for the lines)
Oh almost forgot to mention, Cindy 99, Trainwreck and Super Silver Haze clones will be arriving this week as well, so stick around!
