If the plant isn't fert burned, it won't have any chemical taste, doesn't matter what brand the nutes are.
Nutes is nutes. There's very little difference between nutrients. The main difference between brands is that larger makers will make larger batches at a time, reducing the variability between jugs of the stuff, as opposed to nutes mixed up by your local hydro shop in their back room. Despite potential variabilities from small batch nute makers, I've seen 'house brand' hydro shop nutes grow perfectly fine plants.
However, the plant's requirements are the plant's requirements, so what's in any complete nutrient will not be terribly different from maker to maker.
