How much Ca (w/ or w/o D3) 4 beardie eating bsfl?

Hi! I’m new but have been lurking for a while. Our family’s beardie is Newt and he is 9months. He is a rehome and has been w/ us for 2 months. He’s currently 13.5 oz and 15.5” (he’s gained 2 oz and 1/2” since we got him). He is in a 75 gal bioactive enclosure with elephant bush and opuntia that he likes to nosh on. I have a 130w mercury bulb for basking, highest temp 110-115, a 75 w Che that runs 24/7 and 75 watt white bulb for added heat. Low temp side 75-80. Also there are 2 24” slim tube fixtures w/ t-8 10.0 uvb. All bulbs are <2 months old. Lights are on timer for 6am-9pm. At 6am he gets a salad of mustard greens, collard greens or dandelion greens and acorn or butternut squash (alternate it to keep him interested) I also add a bit of carrot or peppers to keep it interesting and once a week blueberries or apples. Oh and bee pollen. To this salad I add 20 bsfl at bottom. When we get home 4pm I take him out and offer discoids (2 or 3 at most) and as many bsfl as he will eat in 15min. He hasn’t been eating the discoids so I put those back and give him bsfl. Occasionally he gets a superworm or hornworm. So here’s my question: I have Ca without D3 Ca with D3 and liquid spray vitamin Zilla brand with betta carotene. Can someone please help me figure out what schedule I should use for the supplements? I’m worried about possible Ca overload. Thank you!

I would do with D3 2 X a weel lightly + without D3 the same. A mulivit 1-2 X a week, but all dusting should be very lightly, esp. the vitamins.

BTW, sounds like a very interesting enclosure and I'd love to see pics. Can you post pics of it ? Here's how :

Hi. Thanks for your reply. I will try what you suggest and I will also try to post the pics. In the meantime if you go on the Amino app under the reptile group you’ll find me under the same username.
