hey since you are growing organic, you can try to either construct your soil so it's the right pH, or you can just sorta add some stuff on top to alter the pH of soil you already have your plants in. dolomite lime raises your pH, but makes it so it never goes over 7, which is great because the proper soil pH is about 6.5. top soil is also very basic, so it makes a nice mix to ur soil if it's too acidic. to lower your pH, you can just put a couple drops of plain white vinegar into the water you water your plants with, or you can mix some more peat moss into your soil. hope that helps a bit.

Hey guys heres my prob.I have posted a few times and glad of the help.I recently put my 7week old seedlings in my grow room,they are in bio bizz all mix.Well i recently gave them to much grow and the tips are yellow on some of them.Also they got kinda heat stressed at a temp of 100.Apart from a cpl scorched leaves they were ok.Anyway i wont to flush them but the guy in the grow shop said i didnt need to do the ph cz it was already set at the right ph.And adding ph water will mess it up.Granted Rating: 5
