Hey guys thanks for any responses. Any advice or info is much appreciated.
I have 2 rooms with the exact same strain ( NYC diesel) and the same medium( promix , organic soil , perlite , dolomite lime (2cups per bale) and bone meal ( 2 cups per bale of promix). They have the same nutes Advanced nutrients Organic line ( iguana juice etc.). Room A is 1 week behind room B. I tested the runoff yesterday and roomo A is 5.2 pH! And 1200 ppm. This room had some leaf twisting , which is why I did a runoff test. Room B which has no twisting but is a little light green for my liking. Ok here's the weird thing room B has runoff of 6.3 to 6.5 (perfect) and a ppm of 200!. So I figure the ph problem in room A is why the nutes are not getting used and the perfect room is eating it like crazy. I am stumped.

Oh ya room A is week 2 bloom and room B is week 3 bloom . Oh ya also what's the best remedy to balance pH I know dolomite lime takes a few weeks so I want to try hydrated like but have hear terrible horror stories about hydrated lime.
