Deficiency based on lack of or nute lockout?

So they definitely don't look healthy. I have them in a mix of roots organic and coco coir, i didn't have enough soil. Have been feeding them at 1/4 strength with the roots organic. I've been watering with 6.8 ph water but last tike I watered with the nutes I didn't check the ph.

Forgot the pics

They look hungry. Have you checked the soil pH?

No I haven't. I don't have a way to test soil ph.
Would checking ppm of run off water tell me anything?

You could check the pH of the runoff for an estimate. You could check the ppm of the runoff too. It might not be super accurate, but it might give you an idea.

I don't use coco, so I'm not the best one to be giving advice here.

Foremost is a phosphorus deficiency. Likely followed by all the rest. Something you did, or possibly didnt do enough is not feeding the plant correctly. Good news is cannabis is very resilient and responsive to nutrient corrections.

Ok, so I need to figure out the ph of my soil and also the ppm to figure out if it's lock out or not enough nlnutrients? Like if the ppm is high coming out that means there's stuff in the soil right? And how do I measure ph from run off? Like what should it be at?

This is my wild guess based on your first post.
Wild guess...
Coco is causing some kinda lock. Was it conditioned and saturated with minerals?
But thats only a clue not the whole cause.
1/4 strength feed is not enough with coco that has no n-p-k in it. Nor any cal-mag-mn-or anything in the coco!
Your water should be fine you (assuming) checked it is 6.8. Might not be getting enough water. If the soil has been on the drier side consistently it will drain much sooner and much more than what its holding capacity would be if it was wet then dried to moist then watered wet again etc. Giving the observation that its running off already then thinking incorrectly that the water might wick upwards.
Heres the wild treatment. Soak the whole pot, large plastic tote. Deep enough to cover the soil. Till the plant stops floating, settles and sits for 30 minutes. This will flush and thoroughly wet the entire medium, including the possible dry pockets. Let it drain. Remember how much it weighs the next morning then give it a full strength feed, half of it now and the other half the following day. There should be great improvement after that. And can dial in what it needs after seeing its response. Get some dolomite lime too will help bunches.
Dont take my advice, wild guess wild treatment I could be wildly wrong. Just take the direction im giving to look for an answer you feel comfortable with.

So basically you are saying to flush it, in order to start neutral, then start feeding it as if nothing is in the medium?

Yes. Not just start at neutral as in ferts salts etc, but also a functionally moist medium to use your nutes.

I’ve always been told that if you have coco in your mix, treat it as coco. When in doubt in coco, flush the shit out of it with a good mix that has plenty of ca and k, I run 5.7-5.9ph in coco. Treat coco ph like hydro, not soil.

If you are letting it dry out too much you’ll have a Concentration of salts that takes a while to flush and will cause lockouts. Coco has an affinity for ca and k so it will hang on to it and not make it available to your plant. Measuring your run off ppm and ph is a good way to monitor build up. Proper dry back is a delicate game in coco. If I see run off 20% higher than my feed it triggers a flush.
