Help with funky leafs

plant hasnt been feed
water always 6.3-6.5ph, spring water with ph down and epsome salts once
in 40% roots with promix and a little seed starter mix got hot feet at 3 weeks old when put in the 4/10th roots mix
she has been pretty dark green but growing great when i noticed the this rusty areas in new growth

is too much N in the soil locking out K?

could it be led too close? it was about 16 inch i moved it to 24ish

Tough to tell with all that purple, but it looks like the start of Mg def.

CALiMAgic works pretty fast right?
i keep getting them sick about 2 weeks before they get 1/3 as tall as my space
