You didn't answer any of the questions in my previous post, which were essentially the basics when it comes to calcium/nutrition. Please answer them if you want accurate help.
You should be dusting his feeders proper supplementation on a regular schedule. They should also be gutloaded properly. What type of supplementation are you using, what is the schedule, and how are you gutloading?
You should also have a good UVB bulb, which should be replaced every 6 months (12 months for Arcadia). 75W isn't a UVB reading. Wattage has nothing to do with UVB. Do you mean 75W for heat bulb? For UVB, you should have a 5.0 or 10.0 is ReptiSun or ReptiGlo, with T8 tube fluorescent being better than coiled bulbs. If you can afford it, T5HO bulbs are the best, with Arcadia bulbs being the best of the best.

T12
