Also, do you think i should maybe try a dose of cal/mag and maybe some ebsom salts? Maybe it will help?

I cant really say TBH.
Though your nitrogen at 4% on your bottle might be an issue too.
Calmag needs nitrogen. It may be, you have pleanty of calmag, and not enough nitrogen. The excess cal and mag, would keep it around the 7 mark too.
Do you have some veg nutrients with higher nitrogen? Maybe 6%, or so?

Coco and perlite only? That mix is all inert materials. Get some worm castings. I would go equal 3rds castings, coco and perlite. The castings won't interfere with whatever nutes you want to use. Chemical ferts and organics work great together.

Im sure its potassium, or sodium.
Its very dry. Probably almost crisp, and like sandpaper?
Id have a look at salinity toxicity.
Potassium deficiency, and toxicity. Id check that out too.
Imho, its one of those, or both.
From what ive heard, you dont need anything extra with canna coco. Its buffered properly.
Remember too, from the article, organics dont pass through the coco. You need to bare that in mind. Organics will trap, or soak up some nutrient, before the nutes pass through the coco. Not saying you cant, just be wary.
Have you tried contacting canna?

Yes the leaf is a little rough but not bad. I rinsed the coco properly when first unpackaged and did a big flush at the begining of the week which would have taken care of any sodium build up. so im gonna try and target potasium and see what happens. At this point im gonna try a deficiency that is close or possible and move on if nothing works. I have not tried to contact canna as of right now. If nothing works out then i will.

My nutes are clear once mixed. Im not sure about yours.
I get clear runoff.
If my runoff is brown, then usually ive got, sodium and potassium issues. Its the coir decomposing, and leeching.
Is your runoff, coming out significantly darker?

The same for me in my nutes. Maybe just a slight tint to them. As far as run off it is just a bit darker but not too much. What do you do in your coco to fix those issues?

If i give them more runoff when i feed, it eventually clears itself.
Its gradual though. Its better to just ride it out, and do it little, by little, each feed.

You gotta find out, if what you have is deficiency or lockout too.
Adding something may make it worse.
Thats where the chart i posted, really comes in handy.
Its a life saver sometimes. Honestly.

Just a update: plants are looking a bit better but not 100%. I ended up giving them 5ml of cal/mag and i think it helped. Monday i fed them both 1g with a ph of 5.3 and a PPM of 877. Hopfully its just up from here!

Glad its improving
Tbh.
If you're having to feed at 5.3, to buffer the ph in your coco. Thats a big problem. Calmag, if used in excess will make your ph climb. Just like hard water.
Imho.
Try dropping your ppms a touch. Cut the calmag. Add some nitrogen.
See if it improves.
If there arent enough nitrates in the feed. The coir locks up the calmag. Then the calmag just sits there. Ph goes high.
Just bare it in mind. :peace::peace::peace:

Roger that Tim i also bought some RAW nitrogen to add if the calmag didnt work. Next feeding ill drop the calmag and ppm a little bit and add a little more Nitrogen to see what happens

My ph run off was still 6.5 after mondays feeding
Click to expand...
Ph 5.3 in.
Ph 6.5 out.
Equalls ph over 7, in the coco.
Imho.
You have salt buildup.
Go slow. Do it over days.
Feed, and flush, at desired ph. Until runoff reads the same.
Ppms too.
Run to 15 - 30% runoff every time. I go 15 for feeds. 30 for flushes.
Tbh, i consider this coco 101
