deficiency showing up in between watering (during dry cycle)

Hi! I have a question: right now, my soil is still very damp.
ideally I sould still wait more than 2 days if I want it to properly dry out

but here's the problem, I've been noticing some purple-ish spots between the leaf veins today. I'm still on the fence between if those are natural purpling or spots/necrosis but I'm leaning towards the latter..
early/light phosphorus deficiency maybe?

So do you think I should wait 2 days to water and risk the problem getting worse?
Or water both my plants now?
or water a very small amount with a light dose of fert now and then do a full watering in two days?
thanks!

Maybe too hot + overwatering? I can't see the soil but if in a pot, are you lifting them to see if they are still heavy from the previous watering.

I say this because skinnier leaves + the slight uncurl at tips, I am not credible really other than I have made every mistake possible over the years and any leaves I see that start to get wonky like that it turns out I am almost always letting the roots sit in too much water. And those leaves might not be skinny for that type of plant, but figured I would toss it out there for you and let others correct me/give better advice.

Looks like lock out to me Stop changing things so rapidly
Your girl is confused

update on the situation:

can anyone help me out with this?
l would say ph fluctuations if the color of the spot was ligher but it's very rusty brown, even red purplish in some places.
I'm at loss

Looks like K deficiency.

now that would be an easy fix as well as a stupid mistake to make
thanks

Might be an easy fix, depends on why it’s deficient. High levels of N, P, Ca, and Mg are antagonistic to K uptake. a.k.a. Lockout. What have you been feeding/ how often?

I've been feeding a really small amount.
here's the last things that happened prior to this:
I hadn't fed anything but ph corrected water fort the last 2 to 3 weeks and even if no deficiency showed, I decided to add a bit of bloom and calmag fert to the watering. nothing too extreme.
but one of the plants started clawing like it had too much n so I figured it came from the n in the calmag..

So I poured a few more liters of clean ph corrected water with only bloom fert in small amount to try and flush out parts of that N.
which worked as everything unclawed, but now I have those spots.

No way you could get N tox from CaMg and a little Bloom after weeks of RO. Need more info. Why haven’t you been feeding regularly? What soil? FFOF. What fertilizer are you using? Light?

We can't help you without knowing
A: What medium/brand/blend are you growing in?
B: What kind of water are you using? RO? Tap? Bottled? Well?
D: What nutrients are you using and at what dosages?

This honestly looks like nutrient burn to me. Do basic troubleshooting. The first thing you want to do is let the medium dry out quite a bit.. Judge it by weight of the pot(s) if possible. Once you've done that give them just plain water.. Do not start adding stuff assuming it's a deficiency. If the plant looks healthier then it wasn't a deficiency it was either a water issue, nutrient burn or POSSIBLY but unlikely Calcium/Magnesium deficiency.

IDK we just need more info there is no way for us to know what you're doing or feeding it. Also why are you feeding soil in the first place?

I'm so sorry for my lack of precision!
I'm still pretty much a newbie and I don't have a grip on everything yet.

For the soil, I'm using something you'd be hard pressed to find because of where I live.
but I can say it's a light mix with perlite buffered to a ph of around 6.8 also it says it comes with 12weeks of bio amendments so I think that's my problem right there.

my lil brain is slowly connecting the dots and last time I fed I had something similar happen with the spots between the veins so I'm pretty sure I overfed as the soil was already rich enough.

for the water it's hard tapwater ph corrected to 6.5, the plants are under 189watts of leds,
I use general hydroponics flora trio and sensi calmag for nutes and I typically use very low amount because I tend to overfeed all the time and I'm still trying to find the balance.

today my pots felt very light as I wiggled them slightly up and down under the scrog net so I took your advice and only watered with ph corrected tapwater. I'll see how it evolves.
also, I'm feeding soil just because I thought I had to hahaha
but if I don't have to fiddle with bottle nutes and end up with healthier plants then that's perfect!

also, I used to put like 4liters in to get the 20% runoff and it took 4 to 5 days to dry out

so today I only used 2liters (wasn't enough to get any runoff) to aim at a 2 to 3 days dry.
But now, I'm kinda paranoid that not getting any runoff won't help the burn and possibly even make it worse by keeping the salts in.

I was thinking the same thing most issues are lockout the difference is the cause of lockout. Beneficial microbes can help alot in my experience but I'm no scientist

You really only want runoff if the pots are totally filled out with roots. if they aren't drinking enough the runoff is just flooding the roots

That's definetly what I'm noticing more and more as I gain experience in this hobby. I'll try taking care of those little microbes to the best of my ability

They are filled out, the roots even managed to poke through my smartpot's bottom a few days ago.
but If I pour enough to get runoff it just takes one or two days too long to dry.
