If you are doing everything as you have before, it could just be the calcification of this clutch is different. I too use a one to one mix by weight and it hasn't ever seemed too wet.
You say your temp is fluctuating between 87 and 90. That seems like quite a bit of swing. What type of incubator are you using and where is the thermostat probe placement? Is that just a hydrometer probe in the pic or is that the T-stat probe?
All in all they don't look too bad. Some times eggs just look rough but unless they are severely collapsed, I wouldn't worry to much. The surface texture may look awful but unless there is heavy mold it's not usually a problem. I have seen some clutches on here that have looked as rough as a cob and yet they still hatched successfully.
Best of luck to you.
