A concern with the temperatures and using the coil thermometer (aside from accuracy) is placement. The temperature on the basking spot should be measured right on the basking spot, not on the glass/wall at the same level. The same goes for the cooler side and ambient temperatures. As Cathy (Cat 72) said, the basking temp could come up a bit; I would up it to 105 at least. 108 - 112 would be even better, especially if the basking spot is a multi-level spot, giving the dragon access to different temps.
We didn't get the clarification on the ambient and cool side, but that temperature needs to be about 85.
A few suggestions if you don't mind... one thing many folks overlook on the UVB lighting is placing the light incorrectly because it doesn't fit with the heat lamp on the top of the enclosure. Make sure your little guy is basking under the UVB too, otherwise it does him no good and he won't get the benefits. (You mentioned it being on the other side of the enclosure, so I'm just making sure on that one.)
Try what you can on finding the greens your dragon will eat, try the mealworm suggestion, and make sure the greens are chopped well enough; also make sure they're not right under the heat so they don't dry out right away. Feed the greens first thing in the morning, and feed crickets later on in the day. I don't know what your schedule is like, but it would be ideal if you can feed crickets early afternoon and then again a couple hours later for a couple of months; you can back off one feeding and only feed once a day when he's closer to a year old. He should be eating as many as he can in a 10-15 minute period each time. A dragon that age should be eating upwards of 50/day or more, depending on the size. Feeding them later in the day after the greens should help kickstart the greens intake, too. If he's enthusiastically chasing them and good at catching them, that's a good sign; just make sure he's not ingesting sand with that enthusiastic hunting. My male is 'stupid'

and misses too often to keep him on sand; for some dragons, it's just not an option.
To help with keeping him hydrated which is of the utmost importance, make sure the crickets and mealworms you are feeding are well-nourished with their food intake. I feed my feeders the greens my dragon won't eat so he at least gets some of the nutrition that way - it helps on the moisture content and the dragon benefits from their hydration, as well.
Something else to try - when you bathe him (before he's in there long enough to soil the water) move your fingers around in the water a bit to make it move and see if he'll dip his head down and drink.
There are lots of good folks here with lots of knowledge and ideas that might work for you when something else doesn't. Keep us posted and enjoy!
