I have a partly used packet of Phostrogen left over from last year, which has "effluoresced" - ie gone wet in the packet. I have tried it on a plant and it doesn't seem to be toxic, but has it lost its "power" or is it still OK to use? (I'm an old meanie when it comes to throwing anything away! :roll:
Ta for any advice. John N

I've used it in that state in the past. I don't think it can change chemically just by getting damp, after all you do dissolve it in water.
