Tomorrow my Bruce Banner plants will be 2 weeks old. One plant is showing some yellow on the left side of one leaf. No yellow on any leaf tips and no claws. I believe I may have been under watering. My question is should I/can I start using Cal Mag or should I wait longer?

I believe I need to switch to 12/12 and begin flower stage. Tallest is 12in, the average of them all is about 10in. Getting more width than height and the are starting to mingle. Anybody think its a bad idea to go into flower? Tent is 2x4x5. 
One leaf has one blade corkscrewing. Other leaves appear to be in good health and no visual defects per se.
Is it ok for me to trim some of the leafs off so the baby ones can get some light ? 
The dark devil looks like it might have a twist to it's Leaf. It's day 10, 3rd day with descent pH water. Might that be the issue, or should I be on the look out for another symptom?
