1. Looks like edema; caused by too much water and cool/moist air resulting in the plant roots absorbing more water than the leaves can transpire.

It is very humid in the green house right now (lots of rainy days). It is supposed to be warmer and sunnier this weekend. I will set the tree outside. I tried to be careful on over watering. The tree is in the 5-1-1 mix.

If John is correct, then the resolution would be drying out the greenhouse some. Vent it through a small opening and provide a little heat if possible, and the relative humidity should plummet. It'll also help reduce mold potential!

Wiping the dew off the inside glazing will remove a lot of moisture quickly. Just be sure that the water wiped off is bucketed out in some way. When I have humidity problems I blow air across my storm window and the condensate is sent outside.
