I’m slow. Are you saying you’ve tested nutes and water all 3 ways and they’re within a half point all 3 ways? ‘Cause my old cheap stick (two actually) failed me by way more than 0.3 pH.Just a Question, I’m sure none of these testers are absolute in any way, but do you think a blue lab ph tester, a cheap Chinese 4 in one tester, and a chemical color water test can all read the same +\~ .3 (with the exception of the color test…no points there lol) and still be called dysfunctional? Personally I’m leaning more towards nutrient age/expiration even though 1 reference, don’t remember where, stated that nutrients don’t expire. The same effect from the newly bought cal/mag throws me off as it did have the same results. I’ll be ordering a new nitrogen based solution to test this out. Any suggestions?
I did use all 3 tests as I’m boggled with the results. I’m sure it’s possible for them to be wrong especially a subjective chem color test. If I was more than a nubie I would up my blue lab ph tester but I’ll try new nutes first.
You should be able to tell whether your freshwater is at its stated pH - and EC - as given in the water analysis sheet from your community (if they do that in your place). This is usually the first step in mixing a nute solution - filling up a bucket with water. Put the pH & EC meter in, in order to check if there isn't some unwanted stuff in the water. These tests usually also reveil if a meter fails on you and its probe needs to be exchanged.I’ve been gardening for almost 20 years but never gave much thought to this much testing.
Your pH+ is Potassium-hydroxide? If so, 3000ppms would just totally break any sane nute formulation.Ph up gets me close but needs so much that TDS skyrockets to 3000+.
