Sherb Biker clone grow (800w LED)

After coming back from my vacation and expecting some very nice growth on the plants I'm very slightly disappointed. I've grown these plants before so I know the structure and how well they will swell in the latter part of their growth. However these things have begun to stunt. I did make a very slight change to my regiments swapping out H2O2 for bleach instead to sterilize. After reading numerous articles and people ranting and raving about it I decided I would try it for myself. It does appear that it does keep the roots very nice and white and the reservoir nice and clean tables without algae however it comes at the cost of quantity of the final product. I will not be using this going forward.
