I wouldn't change a thing or dim the lights.

A little tip burn is to be expected and 99% of the grow looks on point.

Don't make a mountain of of a mole hill and overcorrect. You can create more problems than help at this point.

Stay at 3x a day and check the runoff more often to see if it's climbing. Within 200 ppm over what you put in just leave it alone.

Thank you @Grownsince95. I was concerned about the lower leaves having them too. I'm on day 50. EC is 1150. Ppm is 550. Just lowered to 500. Everything going in is fine. Runoff also is within 200. What should I bump the light up to? I also heard coco needs an 8hr period of no nutes. Is that true?

Coco plays a trick on us by looking like soil but growing like hydro. Coco needs nutes all the time like DWC buckets do. I see you're using the halos and auto feeding which is awesome. The closer you can keep your root zone numbers to the rez the better. That means fertigating as frequently as you can and not being lazy about having 20% runoff. It's ok if that all comes on the last feeding of the day or spread out over all 3. It's typical for the first feeding of the day to have no runoff and that's ok if you make up the rest later.

The W in DTW is a real drag but it's the essential part of keeping the root zone happy.

I'm bad with lighting advice because once I get to flower I'm usually at 100% because I only have a 200w light and growing photos so we have to make DLI numbers in 12 hrs. When I grow autos I use a 9/3 light cycle to give the plant more dark cycles without lowering the DLI. In my experience I've been able to hit them with higher intensities without any burning or bleaching.
