My First Grow Lindsay OG

For about a week now the nights have gone 12/12 I put them at 1000w in the beginning but they became too hot as they grew taller and started burning the tops of my plants. I switched the lights to 750w until i finish setting up the inline fans bringing in the natural cool air from outside. im hoping that way the lights wont burn my babies. With some help I did some light, minor "lollipopping" and defoliation on all plants. I want to see how the plants react then next week I may continue. So far the plants are enjoying their new feeds.
