im testing with a sunleaves ph pen. it says the tap is 7.5.. i only put enough in for what i thought would bring it down by .5 but it went down to 3.4. but then i check the tap water in jug right next to it and its 7.5-8 again. i will say the pen didnt come with calibration fluid so that could be my problem right there. would the pen compensate or anything because of no cal. fluid so it makes my starting reference point be off? im gonna try the vinegar thing and see if that works. thanks
kboughton Reviewed by kboughton on . ph - cant get it right whatup guys, this is my first real grow and i went dwc. i got 2 lowryders with 2 gallons of water. they sprouted and everything but i cant get the ph stabilized. i got some powdered ph down but i dont know what kind it is cuz it came second hand ina kit. im experimenting in empty gallon jugs with tap water for now but the problem is the ph goes down exponentially instead of just a little after following exact directions. does it even out eventually or should i just get some new liquid ph down Rating: 5
