this is MG in a shaker type container? haven't used that for a while, but i don't think it's all that slow release, but my info could be oldwhat would you say about phasing out the mg? when to stop putting it in? do you need to continually feed with this slow releasing stuff?
in general, the usual recommends are to stop feeding at 2 weeks prior to chop, i use organics which makes for a bit different timing
