Well it’s a ph regulation issue from what I see:
Here is a great article by royal queen. Very basic but to the point.

Could also be BLS, lookup bacterial leaf streaking.
I’ve not experienced that ever in weed but seen plenty on corn.

Those tips sure look burned to me. I think you are way over-loving this girl.

I dunno what you are thinking spraying the leaves with calmag. If its needed, it should be in the nute solution. It's not usually needed, idiots on facebook think its a panacea. I'd stop that right now. The GH hydro mix is usually all you need for healthy plants. I've used their stuff for years, never needed to add anything. I'd stop the fox supplements. I'd change the nutes and run a simple 2/3 strength dead stock GH recommended bloom mix for at least a week to stabilize things.

Mixing brands of nutes is a recipe for failure. Adding supplements is typically a mistake, IMHO. Try a run with a straight, 3/4 recommended strength mix of your favorite major brand of nutes before you start thinking you're smarter than a PHD chemist with years of experience.

To me, it looks like nutrient burn. When the leaves start to grow funny, its usually an excess of something, in my experience. Changes in color are generally more of a deficiency, changes in growth is usually an excess. Again...in my opinion. 5.5 is a little low for my preferences, but messing with the Ph might release a bunch of previously locked out nutes, compounding any excess nute burning.
Again...just my opinion.

You don't say which GH product you are using. What do the labels say about whether they contain calcium and magnesium?

Grow shop owners need to sell shit. Doesn't mean its useful.

I can't find the makeup of flora bloom online. You're gonna have to actually look at the label and deduce whats in it to decide whether cal-mag is even an issue. I just looked at my GH trio stuff, and both the grow and bloom have magnesium. Essentially all tap water has calcium. Unless you're using reverse osmosis water, the cal-mag should be a non issue.

I repeat my prior advice.
