Nute burn or Potassium Deficiency

If you can only water once a day in coco, simply use a larger pot size to avoid excessive dry-backs.

I understand, to be honest everyone I know that grows in coco would water every other day and would be fine I guess. Learning now.

I water 4x per day in coco when flowering.

like some you guys said, I’ll water once a day about half a gal(more if needed) of 1.2 ec on a 5 gal pot, and hopefully that fixes the issue. Thanks for the help.

That’s great, kinda hard to do on 100 plants, never really had this problem before switching to salts.

Set up a simple auto water system, and then sit back and wonder why you didn't do it sooner. Then you can also use smaller pots and less coco as a result, which will pay for the irrigation system.

I had it at some point, basic Home Depot piping and all, it worked but wasn’t really auto still had to come in and turn them on and what not. Then eventually noticed the lines getting clogged or not spraying for no reason, and next day it would work fine again. Kinda got sick of it. Better system I’m sure would work better.

Don't make a set amount of feed to give your plants. Use whatever amount it takes to get significant runoff for each of them. That's probably a huge part of your problem, along with the excessive EC.

What's the purpose of the net?

Yes will do, thanks

Ok guys back for more help.
So I flushed like all of you suggested, started feeding 2.0 ec, it was good for about a week then noticed some yellowing and figured needs a flush again which I did, this time around I have 1.5ec thinking it’s a burn again, but now few things happens, the main branch is purple, and it doesn’t look like a burn anymore more like a deficiency. I just don’t know what. Here are some pics.
Any help appreciated.
Also, going to switch the house and garden cocos, unless u guys suggest something else.

Right now ph is 6.0 and ec is 2.0
I upped the nutes back to 2.0ec
