No, lime is a soil sweetener to be used if your pH is too LOW.
stinkyattic Reviewed by stinkyattic on . Lowering the Ph Hey so I tested the potting soil today and the Ph is around 7, anyone have any suggestion to bring it back down to 5.5-6? I know for large scale farms they use elemental sulfur, but I wasn't sure if that was the proper way. And would that be causing the plant to look lighter in color and start to yellow in some places? Thanks. Rating: 5
