Canuk Couple First Grow

The plants are growing like weeds! I got a new 450W (200real) LED light last weekend so I installed it Saturday as soon as I could. I've left it on the VEG setting because the plants started showing burn signs after only 12 hours of the full strength BLOOM setting. I've been gradually tucking and bending branches on Cookies every couple days to try and keep the plant from growing into the light too soon. I decided to try a LST experiment on the cheese by bending the top 2 inches over sideways. It had grown straight back upwards within 24 hours which I thought was amazing. Feeding schedule is starting to get stronger because I'm only watering once every 4 days and don't want them to get too hungry after the straight water feedings. EDIT: I was chopping some leaves off the bottom of the plant and I think I've found thrips. Jumpy little monsters hiding out on the bottoms of the leaf. I would take a picture but my phone camera quality resembles that of a crayon drawing. How should I approach these little shits?
