Hick said:lime is a "buffer", it works at keeping a neutral PH (7.0) and won't bring it any lower. "Horticultural" lime should be added and mixed in "well" before any plants are planted for it to be effective.
I would suggest lowering your nutrient water to around 6.2-6.5 before feeding. "PH" down...from the hydro store.

ROOR said:Noooooobodies using a ph pen or meter??????
Doesnt have to be digital, just post some quality ph pens/meters....
Dr.GreenThumb said:IMO digital is the ONLY way to go ROOR, want to get the best you can. I personally use an Oakton PH Pen, I have not used any other so I can not comment on the quality but it has worked so far for me.
