Hey guys, I have opted to go straight coco after some debate in this thread (and in reading it through somewhat). I tried posting this in the Plant problem forum but have had a bit conflicting responses. My opinion is there is a cal/mag deficiency, after a bit of research and picture finding. At first I thought maybe some burn. Alternating feedings with straight water.
Noticed these leaves last night after being out for a while with a friend who came into town. Two different strains, similar symptoms. I looked into it and figure it to be a cal/mag deficiency. Growing in Canna Coco using Canna A&B, Rhizo & Cannazyme. Also using Cal/Mag but was using reduced strength for all of them (about half). Leaves aren't too green so I think maybe I could stand to up the nutes a bit and I'm thinking there is a cal/mag deficiency. Also using a product called 'Prime' which I purchased at the pet store to eliminate Chloramine that is in my water. My tap water is 0-10ppm slightly basic.
My temps aren't perfect by any stretch but they are within reasonable growth ranges pretty consistently. My humidity is on the low side (I have a humidifier I am going to install in the tent on Friday) running in the 30-35% range although I am foliar feeding with a really light solution of enzymes to try to keep em moist. Most of the rest of the plants look pretty good in my opinion. I don't think it's a pest (i see no bugs with my 30x loop or 10x or my own eyes).
Any thoughts? Should I just water em with some cal/mag, maybe brew up a new reservoir with a slightly stronger solution (was @ 750ppm wh ich I thought was on the strong side TBH so I thought maybe it was burn at first but it looks more like cal/mag to me).
They look somewhat similar in problem, but not identical in advancement. I could easily be quite wrong and I sure don't wanna be. Help please

The one in the square pot is Sannie's Killing Fields F3 and the one in the round pot is Herijuana. Round pot was actually the most vigorous plant up until yesterday and then by the end of the day I noticed some changes on the other plants as well (as you can see). They are about 2 weeks from seed (I let them stay in the 3x2 cubes a bit too long I think and they got a bit root bound and then I had a little trouble figuring out how to best transplant em, some are doing better than others now my KO Kush x Jackberry got really stressed as I transplanted them first but they seem to be recovering).
