Name deficiency please

Hey guys
Just looking for help in this plant problem
It was great and then it got yellowish then today these spots making me think calcium deficiency
I’m growing in coasts of Maine brand super soil and using liquid kelp when watering
Thanks for the help

Tricky one that. Doesn't look like cal/mag problems I've had. Mine always look like rust on the leaves. Can't ever hurt to give some cal/mag though.

The only times I've ever seen something like was from over watering - although it doesn't quite look right for that. Could water have dripped on them during feeding? Because that can cause something somewhat like that. Or possibly even insects. What are those black spots towards the upper right of the second picture?

Hope you get it sorted bro. Try not to worry too much though - they don't look bad, just like they've got a bit of an issue.

Pictures in normal light if you want help. No pictures with grow lights on. Especially HPS and blurples.

pH?

Could be P shortage, but unless we can see the true colors, it's a crap shoot. Might even be two issues.

Def a pic with natural lighting would help.

looks like a PH problem to me, in the worst-case - leaf septoria.

If you are really desperate, Id say flush the soil really well with a few gallons of RO
and see what your babies do.

Kinda looks like P deficiency,blotches.You need a well balance food ,although just kelp by itself is good its takes awhile to break down.

Arise from the dead! I command thee! ..rise!
