it's very possible to cause nutrient lock up using incompatible nutes, especially in hydro applications. soil is much more forgiving, but it can still cause problem. I use organics and it isn't a problem for me.Will this cause any problems at all?
not uptight, just have had nute lock-up problems. They are no fun to diagnose and treatguys on here seem real uptight about things like that... i think you're gonna get a bunch of NO's
