ChemPak Trace Elements

[el48tel]

That's the label I always look for. I almost alway avoid NH4 based fertilizers and we have so much calcium in our water that I dont need to add much, but I do use a diluted 3 part liquid fertilizer using in hydroponics.

I should have written "If you don't have calcium salts in your growing medium or water then Chempak alone will not be enough."

Being in Manchester, I sometimes forget that some people get stalactites on their taps.

try Leeds .... stalactites and stalagmites ..... continual battle against these
