First Tent, bag seed test!

Week 4 ended this past tuesday the 25th. I noticed the plants both slow down drastically in growth this week. I believe it is time for a transplant. Both had started a bit of droop which I believe I may have over watered. Starting LST this week slowly, planning on tying down once they are transplanted into their final 5 gal grow bags. I have increased the light output 5% to 25 overall. This being a 400 watt light, and drawing around 100 watts. Im guessing that were around a 1000 watts of output?. I have debated getting a par meter as Im really not sure how much or when I should increase the output of this light. I am only using one of the sf4000 lights. Planning on running a full tent grow next with both of these lights. This grow is more of a test. I added Advanced nutrients carboload, as an experiment to see if it really benefits the microbes or not.
