Question about Mother Earth Liquicraft Grow nutrients

I am growing in soil with Mother Earth Groundswell soil, and I went ahead and got their liquid nutes on a good deal, but when I add their low dose recommend 20ml to 2gal of water, it takes my water pH from 7.5 to 5.6.

Is this normal for liquid nutes? Should I let it set out and stabilize? I’ve never use liquid like this before, so I’m not quite sure what to do.

Also can you pre mix a larger batch, say 5 gal of liquid nutes and let it set through a few feedings if you have an air stone in it?

Yes most nutes I'm pretty sure will drop ph u will need ph up and down just in case
If it's the performance mix it's kinda good I'm using it this grow its my first ever grow and only had a problem i had was in seedling stage bc I stunted them

It is completely normal, and you should be just fine. Liquid nutes are always acidic. Any good container mix will have enough dolomite to buffer a 5.6 feed without issue.

Are you saying at that pH level I am good to feed, or should I pH up? I’ve been told both but I’d like to hear some more opinions.

You will get both sides. I personally wouldn't bother. The main things that control soil pH are the microbes and lime in it.
I have never noticed a pH drift in containers worth worrying about until after 6 months of use.

Before I left for work I mixed up a few gallons and the pH was down under 5.5, and when I got home 12 hours later I tested again and the pH was at 7.1, so I guess I could mix it and give it some time to stabilize.

I wonder if it would stabilize in my soil if I put it in there while it’s low.

What pH meter are you using?

I'm in this camp...if in soil no need to ph anything. As long as you don't overwater or over fertilize a good soil will buffer just fine.

To me, it sounds like you may not be letting the meter sit in solution long enough. How long are you letting it sit in the solution before taking the reading?

it’s pretty quick to change to the reading, I’ve checked it and calibrated it, but I let it sit in for about 10sec and swirl it and wait a few more. Basically until it stops changing, so if there’s any fluctuation in the reading I keep it in.

When I put the meter in the mixture it goes quickly down below six then moves slowly.

After letting the mixture sit for about ten hours while I was at work, it was at 7.1 when I got home, so maybe I could just mix it and wait a while then feed.

I have two separate water reservoirs, one in my garage for outside plants, and one in my basement, the basement one is cooler, garage a few degrees warmer. I mixed two solutions of exactly 2.5ml nutes in 1qt of water, and my basement water source went to 4.3ph and the garage source was at 5.9ph when I tested immediately.

I’m not sure if that has to do with the few degree rise in temp, or if this could be a bad batch or what, but I think I’m going to try and return it and go back to rep tea, because Mother Earth hasn’t responded to my emails for over a week.

I tried to let the solution sit again and the Ph didn’t move, and the ppm was up around 3000 (and this is the lowest dose feeding), and EC was at 3, so I don’t think letting the pH sit and stabilize is a good option.
