What looks like N def. but starting in new growth, leaves pointing up aggressively

Hey guys so my plants were looking a little pale Sunday so I fed them for the first time, and now today they look much much worse and I'm not sure why at all, any and all advice would be greatly appreciated thanks in advance!

could look like Mg deficiency, you decide, if so, some Epsom salt (Magnesium sulfate) could be the answer

A normal feeding wouldn't add enough? And would it be bad to add some Epsom salt so soon after the feeding?? I'm afraid to do much, it's my first time around if you couldn't tell

Is the angle of the leaves a sign of ph problems or anything else significant??

No. They are reaching for the sun/ light.
