Bananas love rich organic but well aerated and well draining potting mix. You can mix CHC with some compost for that purpose. Bananas will thrive very well on same potting media as citruses.
There is, however, a huge difference between the fertilizer needs of bananas and citruses. Citruses generally require 5-1-3 ratio while bananas require 3-1-6 ratio. This means that bananas needed twice the K compared to N. Bananas can tolerate various ratios even when potted, thus a 16-16-16 should work also well. But if you need fruit production, use the 3-1-6 ratio. Bananas are heavy feeders of K.
Apply fertilizer every week during the warm months and only once a month during the cool or winter months, provided you keep them above freezing.
