If Ahrlan hasn't had his rodent block in a few months, that could have caused MBD. He's eating a good selection of veggies, but 1/4 tums once a week isn't enough calcium, and the corn and chippie mix will be very high in phosphorus. Plus spinach interferes with calcium absorption. Spinach is not recommended on the Healthy Diet.

I'm afraid it looks like with his current diet, it COULD be MBD.

Crush up the Tums in water and get it down him. One whole Tums. I agree some molasses or something sweet rubbed on his gums can help too.
