I realise you are currently online, so I have privet messaged you my skype details. It will be quicker to solve things that way.
And now you are offline lol. Anyways....
I should have asked before how old your beardie is. Judging from your images in the other post I am guessing around 7months.
From the little bit of research I have done on calcium spray, it appears that it is very watered down and not as effective as powder. Many people have problems with coating roaches with powder well, but even a light coating would be better than nothing. What brand of powder is it?
Basking temp looks spot on, cool side seems a bit low but should be fine with a good gradient.
The salads are good. The aim is to stay away from a staple with high amounts of oxalates which is what you have done.
It is quite possible that the MVB could have contributed to this. It does take some time for MBD to actually kick in, and your new globe could only start working and taking effect.
The type of coil globe I was talking about was something like this:
They put out a dangerous amount of UV and loose effect quickly (about 1 month)
Ofcourse it is hard to speculate but this is what it sounds like to me. Whilst it was hot your beardie was getting natural sun light keeping vitamin D up, and your globe could not have been doing the correct job. Now that you can not take him out this could be part of the problem. It could also be possible that the globe you switched to could be faulty. This is obviously hard to tell unless you actually test the uv yourself.
I strongly suggest trying to use the powder, even if it is only a little bit on the roaches. The new reptisun globe could take a bit of time to kick in, but you need to make sure there is enough calcium provided. It is not to late to reverse this, but I honestly feel like this is the starting stages of MBD. We could speculate on why this could be happening, but I think it is better to be safe than sorry. To much calcium can be just as harmful though, so try not to dust food every single day. Depending on age it varies but generally 5x calcium powder once a day, and 2x multivitamin once a day.
