another question: I'm growing in soil...using 2 parts schultz potting soil 1 part vermiculte 1 part perlite and a bit of dolomite lime...the dolomite lime is supposed to balance the ph of the soil if i've read everything right. Does this mean that when i mix up nutes and water that i don't need to PH balance the nute mix before i feed it to them? I'm assuming its better to ph balance it first then feed it to them.
