Then its not your feeding its just maybe tank maturity and your nutrient export is probably in high gear.. a good think but what I did when my nutrients where low was add a auto feeder to the sump dumping pellets 6 times per day near the return pump and using the skimmer 50% of the time. Your nutrients may not be the problem it may just be the high alk. I feel any hobbyist honing their ALK management skills should keep ALK around 8.5-9dkh. Once your confident then go 7.3-8DkH range - which IME reduces any necrosis considerably and results in SPS being able to handle almost any kind of nutrient level and light level. Also, I would say sps frags do much better lower light 150-200PAR and as they grow up they will grow faster into the more PAR zone above them.
