I'll try to make a long story short. Decided to splurge on a pH meter:
https://www.amazon.com/gp/product/B01ENFOHN8/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
It's their burdget model, but it seemed like I should be able to trust Apera. The first one Amazon sent was clearly already used and returned for being defective. I bitched and returned it immediately. The second one they sent was definitely brand new. It was within .1 of the included buffer solutions, but I went ahead and calibrated anyway so it would be ready to roll when I'd need it in a few days.
So, I go to finally use it. Even as much as I suck at growing, I have come to have some sense of feel for when my nutrient mix should be around the right pH. So I get it right about to where i think it should be, yet my new meter is saying it's 7.2. Seems a little higher than expected, but I go ahead an add another mL of pH Down, thinking that should put me right around 6-ish. PH meter now tells me it's 7.0. This just doesn't seem right, so I. decide to get out my GH pH indicator drops and see what they say.
They're showing a nice bright piss yellow color, telling me I should be right around 6.0. Decide to recalibrate the meter (even though I'd just done it a a few days prior). It doesn't seem to like the 4.0 buffer solution, but after a few tries I get both parameters - -4.0 and 7.0 - set. I test my solution again, and it's now saying 6.7-6.8. Meanwhile, my GH drops are still turning the sample bright piss yellow.
Which leads to my ultimate question: Which would you trust? If close enough is the absolute best I can hope for from this meter, I may as well just return it and stick with the drops. What do you people think?
