STN or is something picking on these?

I have about four colonies doing this. Different locations.

I turned my t5 lights down from 10 hours to 2 hours two months ago and just bumped them up to four hours about a week ago.

Alk has moved some but I turned off my doser and it might have drifted .5 in 24 hours.

I just fed the tank 20 minutes ago. Look at the tips on these two.

Low po4?

Negative. Might've found an issue.

P04 is between .16 and .34 on Red Sea
No3 is over 64. Tested twice. Red Sea. Need to get another test kit.

looks like tip and base recession..
could be so many things..
can you give a basic run down your your system, all parameters and husbandry?
could be old tank syndrome, a bobbit worm, odd alk, ionic imbalance..
really tough to tell..
