You said..."has calcium in his food 2-3 times a week and usually there is dust left on the bottom so he gets it pretty frequently"...
It's recommended that you use a phos free calcium powder(no D3) at all feedings but two a month and on those 2 use a vitamin powder with D3 and a prEformed source of vitamin A. All dustings should be lightly.
You said..."I give him the herptivite multivitamin about once a month as that was what the reptile store suggested. Sometimes I give it 2-3 times a month as they are right next to each other when I prepare his food"...Herptivite has prOformed vitamin A not prEformed. While I've never found it to be a problem with veileds, it's recommended that the vitamin A should be ptEformed. Preformed can build up in the system and lead to health issues but prOformed might not be usable enough for chameleons
