@TheReilly25 I don't think the epsom salts solved my problem, because I diagnosed the problem wrong.

It was a low PH, so some nutrients were getting locked out.

The Epsom salts may have helped, but it was vital I got my PH back in line.

The plant did survive, and has a bunch of new growth - but I'd say its probably a month behind where it should be. And lately I've been adding cal mag to the nutrient solution.

I usually flush when i go to flower to avoid that

This turned out to be a PH that was too low.

My PH meter had needed re-calibration for a while, so I believe salt build up was hurting the plants and largely preventing growth.
