PH vs PPM Problem - HELP
Getting my H2O down to 6.0 PH is raising my PPM by 325ppm !!! HELP PLEASE!!!
I am using GH PH down. Can anyone recommend a PH down product that will not raise ppm so far. I am concerned about too much salts, too low nutes. THANKS
Water (tap) 85ppm, 7.1 PH
Temps are constant 70F H2O, 80F Air.
GH 3 part nutes
Hydroton grow medium (very well rinsed)
I am running a 16 bucket DWC- 45 gal res -- 240 gal per min recirc. pump, 120 liter per min air pump (lots of bubbles), Water Farm drip collars on 20min off 20 min. 6.5" bucket lids, 5 gal buckets, 1k HPS Hortilux. 2 weeks into veg. White Widow & Gods Gift
I suggest you concern yourself with getting the pH correct, and let the ppm sort itself out ... find a different water source, perhaps ... for some weird reason, I couldn't get my ppm over 900 or so, (using Fox Farm nutes), unless I really went crazy with the dosages :wtf: ... but, I guess the plants couldn't understand it, either, because they did just fine ... your GH nutes and 'pH Down' are quality products, I don't see any problem there ... good luck :smokin:
Are you checking your ph after you mix your nutes? because you should be they will effect it.
what pete said for sure. GH ph down is really strong for me, strange you would have to add so much.
I would love to have that water. Take a gallon and PH it down then check the PPM's. Come back and let us know. I don't think it raises that much. GH nutes should buffer that water down to about what you want.
