Hi, im 2 weeks into flowering. Im using the full line of foxfarm nutes. my runoff PH is at about 4.5.

Im using 3 gallon pots, and today i flushed them with about 5 gallons of very high PH water, like with a PH of 10. and after flushing my runoff PH was still at about 4.5

how can i make the PH go back up without transplanting them?
