So i've done a ton of research and cant quite figure it out. I had purple growth coming in from the tops of a few and then almost a purplish tint to some of the leaves. I added cal mag thinking that way be the problem but its still happening except now their turning more of a rust color and the leaves are dying. Some pictures looked a little like phosphorous but its only veg? I saw a few threads saying to just flush them for 2 weeks could be some kind of root problem... can anyone offer some help or had this problem before? It's only on 4-5 of my plants, all one strain and then one random one next to it.

1st thing I would check to see if its rust fungus. Rub the spots to see if anything comes off on your fingers.

Doesn't rub off, but definitely looks like some pictures i see online. I also tried adding cal mag for 2 weeks and haven't seen a change just a slight spread of it. I read online that sulfur burning works against rust fungus so gonna try it tonight and then do it again in a few days and see if that doesn't cure it.

Looks like a slight calcium lockout to me. Leaves don't look burnt but I would definitely flush.

I couldn't say for sure. I am pretty new to growing, however I wouldn't be surprised if it was cal/mag. I say this only because I had a similar problem and dolomite lime solved it completely. I didn't have as many spots as you do though, however I might not have had as much as a deficiency. If you can afford it and get it, get some dolomite lime. I read a ton of stuff and was so skeptical on it and then I got it and I can honestly say that it was very beneficial.
