Soil grow: mid 6's
Hydro growz: well yer in trouble if you dont have a ph and a ppm meter

You should be ok, maybe, probably have time. I actally have a little story, b/c im doing my first grow in my *new* house. I was running into all kinds of crap id never seen before, finally broke down and did some ph testing, my tap water runs at about 8.8! its crazy high. So I just recently went thru my first ph experience ever. However, I didnt notice any defs until about the 3rd week in veg and it was quickly cleared by some foliar spraying and yup, vinegar. So you should be ok.
carinia Reviewed by carinia on . How much vinegar should i add to my water for soil grow im pretty sure my plants ph is too high. i used a soil ph kit and it became very dark green. i want it in the yellow. so my question is what is the pH of vinegar? and how much vinegar do you usually add to your water to lower the pH?
