the meter is new and workin fine.i will lower the ppm and just keep adjustin the PH.with reading info on the bottle i assumed i would only have to ph once lol thanx for the info ..
what ppm do ya go upto during flo ?
it also says to put nutes into res an leave for a while , how does that wrk with pumps on 15 on 15 off, turn pumps off for short while to let nutes settle ?
