Sudden problems after a decent start

[Deeproot]

Could someone please give me some pointers on what I'm doing wrong here. Each plant seems to have a different problem. I've tried a few things but at the moment I don't know what I don't know.

A few of them look like you've spilt water on leaves when watering and the light's burned them.

Soil looks a bit heavy? what is it, also, only need watering every 3 - 5 days so you don't drown them or end up with pests flying around ;
