MG Deficiency?

This young lady is only 11 days old, and her new growth is twisting. Is this a MG def? She is in hydroponic drip system, fed three times a day with Flora Nova grow 7-4-10. 1/2 tsp per gallon.
Had a scare with her 5 days in, as she laid down. And looked a little pale. It was a heat thing I think. I raised the lamp, (400 hps) and added another out take fan. She perked right back up. Now her new growth is twisted.
Any other info you need?
On a side note, I'm new to this. If it is a stupid question you can tell me. I have searched the forum for the problem. That's why I suspect MG def.

Any one help an old dude out? If it isn't MG def, what is it?
