Nute burn creeping in, need advice

Hey so like the title says I've started to see nute burn slowly creeping up on my girls in early flower. I reuse my soil and just reamend it but never had this problem before. I'm assuming I've overfed em but I can't take the dry amendments back out (chicken poo pellets, sulfate of potash, bat guano, dolophos, kelp meal, basalt rock dust) and they're under a scrog net.
PH my water to @6, humidity @65%, lights off 16c, lights on 26c.
What do ye reckon? I'd usually defoliate em at this point but I'm wary of it now

I agree about pH issue. It looks like you threw things out of whack with the crazy top dressings. You may have slowed down your microbes.

I would use some EWC or compost to Top Dress or brew up some microbe tea to get your soil life kicking again.

I wouldn't worry about defoliating, your most burned up leaves will probably shrivel up and die. But most of your leaves should recover and turn green again, so hang in there.

This will help.
Hard to see fine details or clues with the light altering the colors in photo.
Also what is dolomite potash. Is it limestone calcium carbonate and magnesium carbonate with muriate of potassium? Or is it muriate of potash maybe a 0 0 20+ something? Kinda looks like a pH issue.

Sorry got that wrong. It's dolophos and sulfate of potash. I'll edit the original post now. Here they are with lights off and the pics of the nutes.

Heres my guestimate treatment.
Dolomite lime would benefit the plants top dress it, water it in well. Especially if you put potash instead of dolomite lime in your reamended soil. Potash Could be too strong an acidifier, locking up, well everything.

This, the acidity makes it hard to microbes to stay alive, (same with super alkaline.)

do you have anything like rootwise or recharge/mammoth p?

Try to adjust with a basic element, and redrench the soil with microbes, you should see them bounce back, look at the new growth, some of the effected leaves won’t regain their color etc

Ye reckon it's a PH issue? Ill do a PH test next watering and see what it's at. I had been using pH down cause my source water is pretty high. But hadn't considered the change when I swapped from bottled nutes to dry. I have a bubbler too so I'll get a compost tea going. Cheers, I really appreciate the advice

WhT kind of Ph meter do you have? You could do a slurry test or you could put the probe right into the soil if it’s the right kind, there’s a tek if you google it’s fairly accurate. I like the slurry test. But it will give u an idea, I’d ignore ppm. I also never ph water. But that’s a different discussion, and only bc it’s living soil/organic

Wait I just read why you Ph down, what’s your water come out at? It might be very alkaline, what’s the ph and Ppm out of the tap?

I've just been using litmus papers tbh. Cool I'll do a slurry test, they aren't due to be watered for a couple days so that'll give be an answer sooner. I'd been giving em microbe tea pretty much every watering but was worried I was over doing it. Maybe that's made a difference.
Im using an open tank in the attic, when I used my old digital pen it read 8.1

Ah tea every watering, hmmm, what’s your tea recipe?

Ok hold on you may be missing the bigger picture here. Watering in soil at 6...that is too low unless correcting a soil ph issue of being a little too high

You should water at 6.5ph. Unless I overlooked something I think you are locking out some nutrients with too low a watering ph.

Molasses plus the ph down

Sorry the @6 meant around 6. I'm using litmus papers so can't give exact to the point reading's

Are you looking to do full organic living soil or another method?

I thought I'd been running organic living soil but now I'm thinking I'm in over my head knowledge wise.
I'd been using the dry stuff I mentioned, plus teas so there'd be microbes to break down the dry stuff. But from what ye have said I'm thinking that my soil PH isnt good, not sustaining the microbes, since I haven't given em a tea in a while theyve died and that's why I'm now seeing issues?

It’s a little touchy but don’t get discouraged, once you find what works for you it will be one of the easiest ways to grow, imo, so I am a little bias hahaha.

but if you want some really KILLER info check out videos by Jeremy from build a soil, and also look into rootwise soil dynamics. Leaning from those two and using their shit has made living soil a breeze.
it can be dont many ways tho that’s for aure

I’ve ditched molasses, so far the plants get watered 3 days a week, Monday, Wednesday, and Friday.
In 15gallon pots (the smallest recommended pot size for living soil, I’d also stay away from smart pots in this grow method) they get 1 gallon each on the watering days, or 4ltr

Mondays are feeding day or plain water (I used organics alive sometimes)
Wednesdays are for microbes
Friday’s are plain water and or aloe powder/coconut water powder
Put yucca in at least one watering a week
Never ph’ed
Never flushed
zero runoff
