Also what a lot of people don't understand is lockout and pH and what is really happening.
Don't be fooled by post truth!
pH of 7.0 is neutral and does not harm a thing. A pH of 7.0 +- 1 is basically neutral and doesn't hurt a thing.
pH of 5.8 is a decent middle that allows for a fairly even uptake so it is more easy to dial in a program. But all it means is the absorption rate of certain chemicals is at certain levels.
That means it is up to the companies to overdose the under performers and under-dose the over performers in their soup to make it all go in at the right ratio.
AN adds buffers that last up to 6 days that help to make sure you keep the pH where they want it for their ratio. But you have seen the charts there is all kinds of absorption rates all over the map.
Now Lock out is a troubling thing but you are in hydro where it doesn't matter. In soil when you cause lock out you have to work hard to fix it. In hydro you do a res change.
But lockout is also redeemable. In soil this is how you really fix it.
Those microbes now have an eco system down there that is symbiotic with the plant and things are different now. Buffered uptake and microbes breaking down locked up salts.
Smoke some weed and be cool. The worst is you res change if it don't calm down. Wait till the microbes all die off and see how she is.
