Yea you have been dumping ph that's way to low in your pot so that's one issue to fix. Do a slurry test and check your soil ph. Probably have ph lockout at this point. Water in your feed at like .3 higher or lower than you want your ph to be to try to get it to start adjusting. Also what do u mean water comes out by the handle of the pot. It's not making it thru the dirt? More reason for ph to be off, soil full of salts. You probably wanna feed till you see a whole gallon of water come back out that pot just this one time. And in the future try to get at least ⅕ to ⅓ of what you put in back out in run off. Will really help with left over nutrients getting out and ph regulation
