Yeah i would, i normally dust with calcium w/o d3 every other feeding and with d3 every other monday (2x's a month). i also dust with a multivitamin every other monday (2x's a month) opposite the d3. D3 one monday then multivitamin the next monday followed by d3 then mutivitamin etc. hope this helps.
Just a heads up btw. You do know that after he gets to adult size 8-9 mo you can cut back on the calcium to every other feeding. I'd still give the d3 2x a month though and the herp 1-2x a month.
