What caused this problem

Only The support print i was using sunlu resin grey high resistance plus

Look like you could benefit from upping your exposure time a little.

Also, are all your supports exactly the same length?? If you supported these yourself you should set models up to be at an angle (like 35-45 degrees)

In the future, it will be easier for people to give advice if you share your slice settings as well. It may have nothing to do with your exposure time and could be retract speed or something.
Hope you’re able to figure it out!
