Well I'm going to have to get a new pH meter soon, although I won't be able to for this grow I'm pretty sure.
The drops just aren't working out for me either. I'm colorblind so they are useless to me and my helper is having a hard time with them too. One time it's close to 7 so I add only 2 drops of pH down and then it's closer to 6. So I add a few drops of up and then nothing changes, I add a few more, still nothing, Add a few more and then it's close to 7 again. So then I add a drop of down, nothing, add another and still no change, add another and still no change, add 2 drops and it's down to 6 again they say.
I'M Fucking tired of shaking gallons and gallons and gallons of water just to find out it's never close to 6.5.
I'm getting pretty tired of this shit and it sucks I won't have any cash unless I get this job, and even then I need to spend the money on Xmas and Bday's.
Well I've learned my lesson not to buy cheap pH pens, but when you don't have the money a cheap one seemed like a better idea than drops to a color blind mother fucker.
Sorry for the rant, just getting tired of having issues with my girls and not really being able to fix it.
