Thoughts on this kit?

[rivx]

I'm looking into growing microgreens for Gracie and I was considering a salad mix that has broccoli, kale, kohlrabi, arugula, and cabbage. I've read cabbage can inhibit calcium absorption more than other things and obviously with her situation recently I want to make sure that's balanced out. She has her usual mix as well (currently bell peppers with seeds, bok choy, carrots, peas, green beans, broccoli, some corn, collard greens, chia seeds and quinoa) which she is nibbling at more and more these days so it won't be the only veg. Does that sound balanced enough or should we go with a mix with no cabbage?

Here's the link if anyone's interested. https://www.trueleafmarket.com/colle...nt=40547504328


Thanks.

EDIT: I asked elsewhere and was told microgreens have less oxalic acid than adult greens, so should it be fine then?
