qiuck question guys ..... i'm useing RO water 20ppm & 7.2 ph with just Maxi nothing else . My ph after mixing comes out to 4.2ph & I have to use 2tsp of GH ph up to bring it up to 6.0 .... is there something else besides the PH up to bring my PH up to where i need it ? was told that Maxi has enough calmag in it that i shouldn't need to add it unless a strain shows a def .... usually in flowering 3rd week or so . just tryin to cut back on the trips to the hydro store for ph up . would molases bring it up & give me the added sugars too ?
