Normal?

This is my method of checking ph. With a pool water tester. A bit crude and also a bit of a guess as you can see by the picture. Maybe it's not good enough?

Yeah those work in a pinch but it leaves a bit up to subjection. I would get a decent pH meter and maybe even a PPM/EC meter. I use BlueLab ones and they're great. A little pricey but they calibrate up each time with no issues and have lasted me years so far.

I think I’ll have to do that. Thanks

Or consider switching to highly chelated base nutes that don't require pH adjustment (when used with low ppm/EC water), such as the AN pH Perfect products.

[Not explicitly recommended by the manufacturer] I've been using for multiple grows and I've seen a few reports of others using MegaCrop 2-part without any pH adjustment. My results are just as good, maybe better, as with pH Perfect. So there are other options to weigh against having to put out a good amount of $ for a good pH instrument and cumulatively putting in a lot of time measuring and adjusting pH (and adding more salts to do this),

Sounds good. I’ll look into this. Thanks
