Advanced Nutrients pH Down 500ml

Love it

This is soo much stronger than the orange bottle brandIn a 5 gallon bucket I put 5 ml of Orange bottle product. Ph went down from 7.30 to 7.05.Next day i put 4 ml of purple bottle product and went from 7.05 to 4. So yes its more expensive but way stronger about 10 x

This product is super concentrated and you only have to use a little to get the desired effect. My favorite PH down product by far!
