Your pH is . . .? @Guccizillaa check the leaf texture.

Leaf texture is ok I guess nothing of the telling with it from my observations. My ph always goes in at 5.7/5.8 and I readjust when it goes up to 6.2/6.3

Lights.
Ppm/ec of base and calmag.
Temps and humidity.
Thanks.

You're short on magnesium.
I thought you were using the 3 part which is worse than the 2 part, so that's good. Not saying either are bad, but for $13 cheaper you could have got the GH trio which has Ca and Mg ratios that are better suited to cannabis and you don't need calmag most of the time.
You're too strong on your base N nute and you need to bump your calmag just a bit or supplement epsom. Either or, but it needs more mag and less N.

I’ll give the salt a shot but I can’t drop N unless P and K come down also with these nutes also is it safe to put epsom salt in the reservoir?

Drop your base just a little then, tiny bit. I wouldn't put it in the res, just a foliar. It has sulfur in it and any that doesn't get used up stays in the res.

Could this be a p/k problem also

Too much K can lockout Mg, Ca, Fe, etc. So, it is possible that overfeeding your base could have locked out Mg, but after reviewing the Mg in your nutes, it's quite low. Running a CMH and QB, they burn Mg up pretty quick anyhow with the increase in transpiration.

Thanks.. I’m starting not to like this lineup I’ve never had so many deficiencies until I started with emerald harvest on this grow

You think is should use cal-mag plus instead of emerald harvest brand

I’ve never used one in none of my dwc grows in the past and never had a issue... this crap has only begun once I switched to a new brand lineup and the strain is pineapple chunk... I’ve been spraying with epsom salt the last few days but things only seem worseHow can you do DWC with no TDS meter??
At weeks 3/4 of Flower and the bluish tint, I'm going with PK issue.
No mention of strain? She looks hungry to me.....

After some more research I’m starting to believe that I am more on the excess side of p&k causing deficiencies in other nutrients... but all opinions will be helpful due to that fact I may be completely wrong
