What are the numbers on the fertilizer you're using? On the banana fertilizer I have, it says 15*5*30.

Mine is 24-8-16. And around July it gets hit with some 15-30-15 (same at the tomato plants since it's annoying to change the cartridge). Otherwise the miracle gro all-purpose is given every 2 weeks when outside since their potted and nitrogen easily washes out during watering. It also has some Osmocote pellets 18-6-12 that's slated for 8-9 month slow release.
I give it foliar applications of calcium only when the tomatoes display the deficiency since they easily show it.
