High!
So far, I do not think I met any pH problems with that soil but it is only my third run with this soil, the soil on probe shows a steady 6.5 that raises over courses to 7.2 - 7.5 for me it is good because I am under LED and I feel they prefer that way.
I am using BioBizz so normally I should not really care of the pH and my water is bottled and at ph 6.5, and I add Cal-Mag and Pro-Cal,molasses
I have been adding garden lime (that I mortar crush, about 2 TBSP for 10 liters) but because of the LED lighting, I am still not there yet some are showing some quick yellowing some others are super green.
I do large batches and got few runts here and there, with some weird early yellowing but picking up afterwards so from what I experienced, I quiet like that soil and happy with the results so far.
Gonna update today pictures...
Hope it helps bro :Sharing One:
Peace!
