Switching light cycle

Depending on the intensity, and particularly in the UV part of the spectrum, 15 inches might be a bit too close.

If you are limited in headroom, consider supercropping the plant. There's a bunch of info on this site, but right now I cant find a link. Essentially what you do is carefully pinch a section of the stem, working your grip around the stem to try to evenly crush the outer part of the stem, then carefully fold it over and tie it down. The damage will heal in a day or so and growth will continue. this way they are still under the light, just not quite so close.

When I had my 5 foot high tent, I found I had to do that for pretty much every grow.

Here’s a pic of some spotting she’s having. Been feeding go cal mag 5ml to a gallon every watering and it hasn’t slowed down. Any ideas? Should I up the dosage to heavy feeding which is 10ml?

Can you take some pics under white light? Hard to make out everything with the LED lights. That kind of looks like deficiencies from nute lockout. How's the pH?
