hi guys, I've been doing a grow for close to 2 months now and havnt really had a whole lot of questions thus far. I have 4 plants growing under a 400w MH set up. inside of a 2x4x5.3 ft tent. I'm using fox farm grow big & also just purchased fox farms tiger bloom. I have a few questions that I would appreciate if anyone or few people could help me out with. my plants are about 7 weeks old, there about 2ft tall, my first question is when I start to flower can I turn the light cycle straight to 12/12? or do I need to ease it in 30 minutes a day as if the season was changing? also do I start to use the fox farm tiger bloom when I do 12/12 or do I start using it before? on the bottle it says to use it with the fox farms grow big formula, but im assuming it means use this tiger bloom for flower growth after using grow big for vegetative growth. my tallest plant from what I can tell is female, she has white hairs coming from some of here colas and such, the other 3 plants are starting to preflower as well but I'm not able to make out there sex at this time. thank you guys so much for all your help!!!!! I will post pictures some time today after my camera chargers.
