I've not heard of yeastex.
Most nutrient makers only provide the most basic ingredient list, at least Lallemand provide both an ingredient list and the amount of nitrogen it provides for FermaidK.
As far as I'm aware, there isn't a substitute (well an "off the shelf" substitute anyway) for GoFerm. It's basically a combined nutrient with no DAP (I haven't checked the ingredients recently - too confirm that), because DAP is considered injurious to the yeast in the very early stages of development. Now that might be just complete marketing bollocks, just for them to sell more of it etc, but there does seem to be at least some research involved with it.
It's designed (apparently) to help you make the most of the abilities of your yeast, but if you can't track any down locally and don't want to mail order any, then if you just rehydrated your yeast as the pack says, then pitch it, allow it a day or so to start doing it's thing, then add half to 2/3rds of the nutrient requirement for the batch, also check the batch with a hydrometer reading, then stir it daily until it hits the 1/3rd sugar break and add the rest of the nutrient for the batch (after it's been stirred/aerated), before airlocking it off to finish......
