Default How to get rid of magnesium defiency in coco?

Iím using heads lucas formula which is 6/9 of floramicro/florabloom which Iíll call M/B of 6/9 ratio.
Also one gram of Epsom salts are added and that brings the following
N-97
P-60
K-105
M-61
Ca-97
S-61
The idea is to keep K low and keep K>Ca>Mg so the coco cations can change without locking out any needed nutrients.
Coco can be a pain to dial in because sometimes the defiency is caused by not enough calcium or magnesium not letting enough NPK to get absorbed by roots.
I have red/purple veins going up stalks,then branches are turning reddish purple.
Leaves show either N defiency or magnesium defiency plus new growth stays small and darker green.
So a lot of small leaves up high but not many big fan leaves.
I was thinking of trying Epsom salts but how much I donít know.
Ay suggestions?

If you are using LEDS it is normal

I've run canna at 10-12 all they way through with nothing extra, plants come out great. Never ran with rhizo though def seems unnecessary, are you supposed to use that much? Ive heard its not that great except for foliar feeds, maybe try cutting that out.
