dust the all bugs you feed the cham at once. dust calcium without d3 every feed. calcium with d3 and multivitamin should alternate, once a week every week. (2 times a month you will dust with d3 and 2 times a month you will dust with multi) never mix dust. (never dust with calcium without and with d3 or with multi in the same feed)
personally I do the above routine except I dust every other day. my cham is wild and I use wild bugs so I have determined this is the best routine for my cham. he is as healthy as can be. to me it all depends on your lighting (natural or uv and the bugs you feed him/her)
