Take a Look Please : Leaf Discoloration

Some in coco, some have some peat mixed with them. Same nutes for both (oops). Some pests as well, but getting them under control.

What does the yellowing indicate please?

I can’t fully tell, but it may be Mg, K and P def. Bottom left looks like Mg def. Not overwatering, are you? Some of that medium looks saturated. Hopefully you aren’t feeding too much N and locking stuff out.

I think that is the case? What should I do from there?

Dilute my feed basically. I'm running Canna A & B in equal amounts as per instructions on bottle. But was feeding daily which was probably a bit eager at this stage.

How wet is your soil? Let’s start there. How often are you watering? Because I’m suspecting it’s water related. If it isn’t water related, you need Mg, P, and K.

Might be cal mag deficiency. I give my plants cal mag every 3 days when I put nutrients in the soil. Just follow the instructions. Also make sure you arent getting nutrients on the leaves when you are watering and that you dont have too strong of a fan blowing on them- it should oscelate to avoid windburn.

Yeah I'm using tap water, I don't know anything about it to be honest. The soil is pretty wet, and I agree on that maybe being a factor.
I was feeding daily, have not fed at all since posting, will feed with diluted next time. I think it's lockout.

I'm going to check pH when I get a chance, I haven't done that before on coco but I'm sure there's a video out there.

My fan is blowing direct 24/7 and I don't have room to make it oscillate I agree on it looking like cal mag deficiency but I thought the canna stuff had that in it. (Just checked and it does.)

It's a really common problem with potted soil growing, it's a really good idea to add that to your water before you add your nutrients. Tap water is good, that's all I use. And as for the fan, if you dont have the space- point it towards the floor or so that the air moves around the tent. Never have a fan constantly blowing on one plant or you will notice windburn soon enough. As for your space restriction, you can look into installing a grid wall to mount a 12" oscellating fan on, it works quite well. I have the bottom of my grid support on light chains wrapped around the main weight bearing pole on the top of the frame. The cheapest grid wall you can buy is for customizable shelving units (mine is Husky brand). Good luck with your grow!
