Indoor Leaves yellowing at margins. Tips dying. LOS organics

Soil slurry pH results aren't great.
The rest of my unused soil slurry tests at pH 7.05. - The soil from the Diesel's pot slurry tests at 7.24. This is using distilled water for the tests.
Re tested my water at pH 6.3, so I may have some luck just flushing the pot, which I'm doing now.
A high pH won't lock out potassium, so its either EC related, or I have a simple deficiency.

Calcium, if built up or over available in your mix could also be an issue. a high pH could cause an excess of calcium, which can aggravate K lock out.

Something to ponder.

Ya know... was thinking about it, not sure flushing here is going to help unless there is something in the flush that's gonna stick to help balance and buffer the soil.

Thanks again for those points. I'm definitely still learning, and issues accelerate the learning curve, which can be a good thing! I want to learn how to fix stuff.
Im going to continue to flush a bit I guess. Then add some organic general fertilizer and water it in, for quickly available nutrients.
I would like to top dress with some wood ashes, but that would bring the pH up further, so I may need to stick with compost and alfalfa and kelp meals. I could also try some soil acidifier.
I'm going to mulch in some Pine chips as well, they work well for me outside.
I think also that the relatively high temps and low humidity aren't doing me any favors.

Got lots of good vibes focused on your setup.

And your right, problems help to hone the skill, but one at a time please!

I just did a slurry test of my new batch of soil, and I feel I got it a lot closer at 6.23. That batch has the following:
2cu ft CSPM
1cu ft COM Lobster Compst
1.5cu ft perlite (still looking for a good local alternative)
1/2c azomite
1c gypsum
1c rock phosphate
1c alfalfa meal
1c kelp meal
1c neem meal
1c crab and lobster shell meal
1/2c blood meal
1/2c bone meal
1c dolomite lime
1.5c crushed oyster shells

The amendments in this mix are (edit- NEARLY) the same, with the difference being the new mix uses just Canadian sphagnum peat moss, compost, and perlite, with none of that pesky, recycled Fox Farms soil.

6.23 is fine, especially to start off in, keep an eye on it thru the grow. Increasing over the entire grow up to somewhere in the 6.5 to 6.7ish in flower as the need for P&K increase.
Peet, as it breaks down, will drop the pH.

Might also look at something like recharge microbes. I use it, and it does what it says. Better looking plants in 48 hrs.

Thanks! I appreciate that. I've had good luck overall since I started growing, and I love a learning experience, but I agree - one at a time!

I'm pretty excited about the new batch of soil, but it needs to cook for a while still. I'll keep an eye on it.
Budget is very tight right now, but I was happy to see that they sell smaller packs of the Recharge Microbes, like the small pouches of Mykos they sell at my hydro store, on Amazon. Going to get some of those for sure, especially because I haven't yet bought a good air pump for making AACT.

The small one, I think 8 oz, will last me 1 indoor run in the 4x and a couple plants outside as well, going on their schedule.

They put out some pretty good info on their YT channel too. Decent people in chat.

I ended up flushing with about 5G of tap water. I wanted to make sure I eliminated any dry spots. If anything, I've been erring on underwatering, I think.

I then removed the perlite mulch layer, top dressed with Compost, kelp, alfalfa and scratched that into the surface. Then covered with some used pine mulch from another container and worked that in a little. I then lightly watered with molasses. The picture is right after watering, and she is very droopy.
