Primal Punch Grow

I've finally got the drip system up and running, perfect time too because they are definitely drinking more. They are getting fed 4 times a day at 1 minute increments which comes out to about 100 ml per feeding. The plants have really started to take off, roots are coming out of the bottom of the cubes. I just topped all of them so they'll start branching out more. I'm currently running a 600w MH and am starting to deal with heat. 2 weeks ago I ordered a ChilLED Growcraft 600w LED light, I can't wait for it to show up so the heat will drop and I can get back on track with the proper VPD. I also just recently ordered Mammoth P microbes and some silica. Hop you all are enjoying the grow so far.
