Plants suffering? Help!

[Irish.OG87]

I feel like I'm missing something. I've had tank up and running for 4 weeks, cycling is just about done. I feel like the plants have helped alot with ammonia being low during the cycling but now i feel like after 2 weeks of having the plants in tank i feel like they are not doing well. Some black spots appearing on plants, losing leaves and some just melting.
Any help would be greatly appreciated.

Most plants are grown emersed, so there usually some die off as they adjust to being fully submerged. I don't know about the black spots-- pictures may help.
