I've recently done this with
Osmocote slow release plant food inside 00 size gelatin capsules and have had no issues at all.

Just make sure they are buried deep in the substrate and don't come loose (otherwise you could have an ammonia spike).

I prefer the clay+peat fertiliser balls now, you can make them yourself, or buy them cheaply online too.

Osmocote leaves little platic balls kicking around the tank and fish/snails dig them up sometimes, whick risks ammonia spikes, so I don't like using it anymore.
