Help with Beet Pulp

Hi,

I have an underweight, pregnant TB here, plus a hay shortage.

Am adding a Beet Pulp slurry to our grains, but can't come up with a balancer for the excessive calcium in BP.

All the grain mixes and supplements I find have the regular ratio.

Can't seem to find a simple phosphorus supplement.


 suggests a garden store. Any other thoughts or recommendations?

Please help.



Thanks!



I didn't find the right solution from the Internet.
