yep, that's the one I've gone for. Used it >10yrs ago, when TNC was a little start-up company and one of the owners (I think) was a member on here.A comprehensive liquid fertilizer will help five the plants a start. You are in England, so look for TNC Lite. This can be used with or without fish in the tank.
Now that the Fish Wallet has been opened, I'm itching to spend more money......on a 'tank that wont cost anything' promise I made to my wife (which has already cost ~£40 on plants and substrate).
a group of ~10 chilli rasborra, maybe some shrimp, maybe a pea puffer instead.....oh dear, I've got the bug again.
