hard to tell but autos are touchy. Dial back and see how it responds. With lockout it's kinda tough to diagnose with multiple symptoms present. in future, i'd wait for some hint of need before giving fertilizer. OF, for example, is a very hot soil on its own. It may take 6-8 weeks before you need ferts. some hint of yellow underneath... just a hint of deficiency and next irrigation fertilize. keep a tighter pH. ~6.8... just slightly acidic is best. 6.5-6.9 range is fine.

You temp is good and your plants look well overall. Those burnt tips could be from having too much N. It could also be that the temperature at your canopy is higher than you're measuring. They could be getting a little heat stress.
