If you ever take some of their Grow Big or Tiger Bloom ferts and spill a little and let it evaporate, there is a ton of salt left behind. There's no way that all of shit is getting rinsed out of a container by normal waterings, it will accumulate. I can understand their recommendation to flush periodically...
Miracle grow potting soil does the same, you can see the salt residuals left on top after watering....not a good thing imho.
