Common use fertilizer used to come pretty generic, like 8-8-8, 10-10-10, 13-13-13, with little-to-no micro-nutrients. Last spring I started seeing something different, like 10-10-10 with "up to 8% sulfur" and "up-to-12% chlorine". That's not MICRO-nutrients! I contacted the factory and asked why, and got weird answers. "Soil needs sulfur and they are eliminating it from industrial smokestacks", and "Don't use chlorine if you plant tobacco" (what about veggies?)

Have you heard anything about all this or am I the only one who noticed the fine print?
