A few things can lower pH.I just moved to powdered nutes
Kristalon brown
Calcinit
Epsom salt
in rdwc I'm experiencing PH drops like i've never seen. anyone have any idea why this could be?

thanks pal i've read a lot of your posts you clearly know your npk's lolA few things can lower pH.
What is your water like? Much buffering to it?
I see a lot of K. Plants will take it quite quickly, and it could be a lot of what holds your pH high. Until it's gone.
Late for work.. gone
Not a lot you could do. I would watch for signs of excess K in the plants though, to see if it's a possibility.thanks pal i've read a lot of your posts you clearly know your npk's lol
how would you combat the quick loss of K from the solution? theoretically it should not be an issue though because I've got a top off res on a float valve constantly feeding a fresh solution as they drink.

I will do that and seeNot a lot you could do. I would watch for signs of excess K in the plants though, to see if it's a possibility.
I'm drawn to the silica comment about bubbling.
I would mix a liter of feed, both with and without. Leave them a few hours, and see what you have. A side by side test, that doesn't involve the plants at all.
Thanks for sharing this. What I used was potassium silicate, which is again, K raising pH. However the bubbling sounds like a chemical reaction. Not the plants taking it. I can't say what the reaction is, but the K present seems interesting.I will do that and see
After a res change out with zero silica things are perfectly stable (for now) so clearly silica is the issue, I also tried two different types of silicon and had issues with both. ph dropped much slower with the shogun silicon but as soon as I added mills the PH dropped like a stone.
I had no issues when using shogun silicone with bottled nutrients from the shop, but switching to the kristalon / calcinit combo seems to give ph problems
