I'm in the camp with JennKK2, CBD/Hemp/Cannabis may be related, but are different.
This may be the bank's opportunity to spell out the differences and determine what it will do for legal entities/customers dealing in legal products, or to as a policy say these are similar to (as an example) MSBs in that there is more work and risk than the bank wants to accept and to refuse all such accounts.
I see less risk in CDB products, labeled and periodically tested. Hemp may be acceptable, depending on the status of the product. I understand that if it's being grown and the crop is what you're depending on, the weather and water it gets can make it usable or not as it can take on properties that remove it from the hemp category (I may be over simplifying this, I was never an ag banker).
A question for the bank is, what are you comfortable with and do you want any part of the market or not. Having one account may be a good test of what resources will be needed.
My opinions are not necessarily my employers.
