Hey Steve,
Just came across this post. The fertilizer I use and stand by is called Growilla. They have one for veg and one for bloom. It comes in a powder form and is super easy to use and it is organic.
Out of curiosity is there a reason you are burying the cloth pots in the ground? When using the cloth pots I just leave them above the ground. This should also alleviate too much moisture in the root system. Let it breath. 😀
