Hello there guys I have a 10gallon fish tank res filled w/ 4 1/2 gallon of water/ ferts. I am doing an aeroponic grow using 1/2 strength Fox Farm GB,TB, and BB + Hydroguard. My sub. pump is rigged to go off for 15 minutes every 45 minutes, my timer is for 15 minute increments only. This whole thing is taking place inside two rubbermaid totes stacked on one another. My problem is that my PH continuously rises higher and higher if left uncorrected. It may be because the frequency of the watering, or something else I really have know idea. I don't even know what to start suspecting it to be. So can you guys please help me figure this shit out and fast. Ask any questions regarding something I may have left out due to my stoner ways. Thanks you fellas.
