Looks like a little too much nitrogen (dark, waxy leaves and burned tips.) Are you monitoring runoff PPM?

In range for soil. Run off or slurry test numbers would help

depending what kind of light you are using. Did you check out the Grow guide? It helps me out a lot.

First, yes, she will be ok! She needs less nitrogen - cut the amount you are giving of nutrients, especially if you are giving them full strength. Autos often need less than their photo sisters.
She could also benefit from a drink with Epson Salts - 1 tsp/gallon of water is a good ratio.
And WAIT in between trying things. The leaves that show damage will not “heal”, just watch the new growth for proper color etc.
She’s a decent size, and you can expect pistils soon if you’re not already seeing them.
It is not a light issue.

Toxicity is corrected by flushing 3 times the pot size with PH water. Run off numbers are usually known prior to flushing so that a good PPM and PH range is targeted. Agree with @Aussie_autos on the deficiency and toxicity

You would flush ur meduim with ph water about five to ten ltrs but while ur flushing i would put two tablespoons of epsom salts into ur water so u can flush and treat the magnesium def at the same time
