I'm growing my first hydro grow in a 6 site DWC...i am using silica stone as my growing medium, and bc nutes...i am having trouble keeping my ph at 5.5, in fact within 2 hours after lowering my ph it's back up to 6.9-7.0. I rinsed the stones and changed my reservoir, but my clones are only in their 2nd week in the hydro setup. i need a few suggestions on how to keep the ph down...btw the clones are ST #4
