Lower your temp to 99-98. Just barely adjust the temp and open the inc. breifly! I know that on this forum that's taboo, but I believe that it will benifit you! If a humidity drop is a concern put add a Tbs of hot water to your humidity source and the brief opening of the inc will not cause harm. Wait and hour and see if there is a difference and I will check back here in an hour. Remember, you are not looking for a huge difference but mayby a crack in the shell that wasn't there before!
