Ph dropping bad

I started my ph at 5.8 earlier today and about 6 or 7 hours later im at 3.6. Whats up with this?

Mine tends to drift up slightly by a point ot 2 maybe you've not mixed it well enough or there is some sort of reaction with the nutes you're using

What kind of water are you using and are you using an air stone? I just solved a massive ph issue due to using ozonated water and not letting it sit before adding nutes. Even after that, with an air stone, it spiked the ph drastically within a couple hours. No air stone solved the problem

The salts in nutes are lowering your ph.. Many variables tho like what medium are you using and what feeding schedule do you have? I usually do feed flush feed flush.. You dont want those salts sitting in your medium and building up.. Especially if the ph is off which in that case no nutes are getting absorbed by the plant.

When you do flush pull the ph upwards by phing the water to 6.8.. 2 gallons for every gallon of soil.. For example if you have a 3 gallon pot your going to want about 5 gallons of phd 6.8 water it should bring your ph up to atleast 6.4 or 6.5.. After this add cal mag to your last gallon and maybe light nutes.
