Hello all,
In my previous grows I never PH tested anything, I just did it all by checking condition of plants etc.
This time around I have invested in a PH pen (haven't got EC reader yet), tested my water after calibration and it's sat around 7.0.
I'm presuming after adding the nutrients this lowers the PH level, not raises it? What if the PH is still not lower enough - what is best solution to lower the PH further?
Do I need an EC pen? Is it much harder to without one? Can you grow successfully without one?
Thanks for your help guys
