Help diagnose please

We had ph issues starting out, corrected that but this damnesia auto I believe is still suffering some type of nute lockout? Theyve been cal mag / boomerang flushed twice at 5ml per gallon... could this be light damage, heat or a combo of bad things?

Phosphorus deficiency

Thank you. Do you think that's all or could it be multiple things. The plants around get same watering and have only been fed twice since I was dealing with nute lockout in the early stages

That’s all I see but I’m on a phone. Others will pipe up soon.

You're likely using calmag for no reason and locking out phosphorus causing your ph to swing and start locking out other things. Such as calcium itself.
Flush with calmag and boomerang? Not sure what that is other than the curved stick the little kid chopped that guys fingers off in Mad Max with, but if you are flushing then you should be using either just water or super low ec base nutes. All you're doing is compliling the problem with every move you make
They look nitrogen heavy. Dark waxy leaves big veins (caused by extra n in calmag that you don't need)
So yes. It's a combo.
Are you growing in coco and/or using ro water? If not then ditch that calmag fast.

Ill likely regret asking but is this water sitting in the bottom of your tent?

the calmag was due to an overfeeding, super high ph and nitrogen abundance issue at 3-5 weeks old. My buddy fed them full advanced nutes for a mature plant so I had to flush the soils These 2 are the only 2 out of 12 still having issues and the others all look great and back on track. Growing in strawberry fields soil from foxffarm , sohum living soils on a few and did a few with a mix of promix and ocean foxfarm. The soil for the 2 rough looking plants is the same as my two that look the best. So I dunno . I think my ph being so high started a chain of issues and I just hurt these two more but saved others. I learn eventually. Lol thanks for advices

And boomerang is foxfarns version of cal mag / root restorer

Phosphorus deficiency

Agreed, but don't you think it looks like it might be Ca deficient too?

 

[rkymtnman]

i'd say the rampant tip burn is probably one of the main issues.

 

[rkymtnman]

Agreed, but don't you think it looks like it might be Ca deficient too?

i'd kinda think 5mL of cal/mg would solve a Ca issue, no?

I was guessing his plants looked like that so he flushed them. But I don't know. Those spots just kinda look like Ca deficiency. I've never actually seen it on any of my plants though since my water already has Ca. Just a guess. Too much Mg can lockout Ca too.

I had read cal deficiency as well when looking it up but I've read bad advices more than once growing . I know a few growers who use cal mag ever other watering like clockwork even without issues just as part of their watering methods

You just gotta read all the advice and pick out what makes sense to you.

It depends on your water source and nutrients. But if I added more Ca I'd have lockouts. I also try to limit my Ca amendments. But I'm in soil and like I said my water has enough Ca already. If I was using RO water I could add Cal-Mag without issues though.
