Veileds and panthers don't really differ in care, though female veileds do tend to make more eggs than panther females. They need the same type of dusting. And yes if you do have a multivitamin/d3 combo only dust with it twice a week and no extra dusting with another d3 supplement. However your gutloading is not a good gutload. Flukers products in general are usually crap, but their gutload offer nothing helpful and possibly do more harm than good. What you want is a good dry gutload and for a wet gut load squashes, fruits, dark leafy greens like Dino kale and mustard greens, sweet potatoes, sweet bell peppers. All insects will get everything they need moisture wise from the veggies and fruit, the dry gutload I recommend if you don't want to research into making your own like I do, is bug buffet, repashy bug burger, cricket crack, Nick barta has a bunch of them for sale in the classifieds section on the forum.
