Bluish Leaves & CO2 w/ Gigantic Picture

Hey, I'm that guy again T-T...ah the pain of knowing myself of myself...

So I set up a little yeast co2 generator and I tested the tube in some water, bubbles came up every 25 seconds or so I think.

1. So I was wondering, did this co2 stuff make these leaves blue or...or is it something else ??

2. If I over carbon dioxide it, what would happen? They'd die, but what kind of symptons or effects first?

Sorry for being a noob, but pictures are aweesome!

What's the room temp? The blue tinge could be because of the cold.

i would put the hose for the Co2 inthe middle of the plant so it sucks it all up. otherwise its looks sweet

72-82F and sometimes it gets as low as 68.

what is the temp of ur fert solution it should be between 68 and 72 degrees and is it airated. and ur lil co2 generator will not pruduce enought to cause u any probs from too much co2. i love makin them they work so well and are very cheap to do. but for much lager then a closet they are not so effective.
