Excellent info! Just to be clear, is the last column Roots Organics or Meigs? I havent sent info for Meigs liquid size yet.Okay, the Meigs lineup (you have added to my database
And if you want to increase your database, I can send you the rest of the label info for the Meigs Liquid line. Ha!
Now Im gonna ponder your formula and how it work...
Oh sorry - I spaced out and put the Roots wgt and volume in the Meigs Sul-Cal-Mag. 
But you get the idea now, right?

I will eventually. Need to study things a bit. So how do I determine the correct dosage based on ppm? How much to solve the problem so to speak...Oh sorry - I spaced out and put the Roots wgt and volume in the Meigs Sul-Cal-Mag.
But you get the idea now, right?
For comparison, you can consult an elemental ppm calculator with advised levels for different growth stages. Greenleaf nutrients has a good one on their site. Let me know if you need any help.
For example, 4g/gal is recommended for normal veg
On the Elemental ppm calculator, 4g/gal provides the following, which could be used as targets for your own formulations.

Still a cal-mag deficiency?
Yep, mostly Mg

Are skinny leaves and thin buds the result? There are a ton of bud sites but..
That’s probably genetic. Sounds like a Sativa.

I'm just gonna throw these all up here! I've been giving these things nutrients (mag) twice a week at almost double the dose. The folks at a local shop suggested it could be some kind of blight but it hasn't spread to the three photos in the tent. They look beautiful! (Fug that blend of hydro dirt. I've learned my lesson!)
I’m seeing multiple deficiencies of mobile elements (N, P, K, Mg) - the plant is pulling these from the lowest leaves because it isn’t getting enough from the fertilizer. Those leaves look like the ones in the shade that my plant gives up on and drains before dropping.
I think the excess Ca (from your previous Meigs mix) may have locked out other elements. Try a flush with a slightly lower concentration (~15-20% less). Then, fertigate as usual with a well-balanced mix.
Your soil may be saturated with Ca though, and not really flush out that well. It would be so much easier in perlite hempy!

That's
That's so crazy! All those elements? And to be fair, those jacked up leaves are spread throughout the entire plant. But definitely moving from the bottom to the top. Here's a picture of the photo plant that is receiving the exact same nutrients. (actually its are only receiving the nutrients once a week as opposed to twice a week like I'm doing with the auto plants to catch up)

I don't know. I'm kinda thinking that putting them in some good ole dirt and watching them grow might be my best move.
Autos can be weird. Your photos look great!
How’s it growing?
You know, I’ve been doing some thinking - and came back and looked at the photos again. And the bluish spots are not exactly something I usually see with mineral deficiencies. The one who diagnosed blight might have been onto something. Has it spread?
