Possible deficiency??

[reddevil6]

Does anyone have any opinions on what this could be?
Coco grow
Ph 5.8
Ec 1.8
400w of quantum Leds
Temp 20 - 26
Humidity 60 - 80%
4 weeks since flip
The rest of the plant looks good besides some tip/nute burn.

What is your feeding schedule?
Do you always feed to substantial run off?
Do you ever give plain water?

It looks poisoned.

2 plants, 1 pot. Likely a game of Rock 'em Sock 'em Robots going on in there. Round 2: Fight!

Yes that particular pot does have 2 plants that's just how that worked out, when I did it i figured it's a big pot (28l) they will be alright haha Mabey not.

Could it be that the roots compete for certain kations and that you therefore would need to take the EC a tad higher, perhaps to 2.2 or higher. Well, not seeing the whole plant now but leaves don't seem to be looking high-fed, and the last of K-def. All these missing leaves were defunct and wrinkled on their own or did you prune them off on purpose?

Yeah that would make sense, I'm bit worried about going any higher on the ec when I was running it at 2.0 all my plants got slight tip burn on the top 3 or 4 set of leaves.
I have just upped the p and k see if that helps.
I have pruned some myself before this started but it's happen8ng pretty quick.
