I'd go with the dolomite if your growing in soil. When you go to buy it, make sure you're not getting hydrated lime... that stuff can be overpowering and easy to add too much. (Had to find that out the hard way... ) I don't know how you'd go about diluting it, I always added it to the soil. Maybe someone else can chime in with a recommendation, or you could probably just do a search for "Lime, pH" and get plenty of good info. Also, don't spike the pH too much all at once, but raise it gradually instead. I know sudden pH fluctuations can actually shock the plant.
Mr. Clandestine Reviewed by Mr. Clandestine on . Raising PH Hi All I'm am using Fox Farm Nutrients at 1/2 their recommended dosage. I have no problems with the PH until I add the Open Sesame. This tend to turn the whole mix in to straight up ACID. PH 4.0 or Lower. I am using a General Hydroponics test kit, and am having to use a large amount of PH up to get it to 6.0 or better. The PH up contains potassium carbonate and potassium silicate. Should I use some dolomite or something ,to up the ph instead of overdosing the potassium? Rating: 5
