My ph shoots up after I flood. It took a dozen floods for it to finally balance out and stop spiking. Is this pretty standard when using lava rocks in an ebb and grow bucket system?
I started a DWC bucket and got a handful of the stones from a friend, and everyday for 4 days my bucket was 7.5 after setting at 5.7. it finally balanced out was about to scrap it. Use hydraton next time.
