You are spot on with your sunburn diagnosis. There's not much shade on my property, which is one reason I planted Bananas.

Thanks for the tip on the nutrients. I'll focus on Nitrogen for the young ones.

2nd picture shows insect damage and leaf edge browning. Again the browning is likely sunburn. And, the insect are visible on the pstem.

These plants are in the vegetative growth stage. They need Nitrogen (N) for green growth; Phosphorus (P) for root development: and potassium (K) for fruit & root growth is not critical, but should be increased as the plant nears fruiting height.

May be this reference can help a little,
