M.P.
W.T. FF?:wtf:
What brand of coco is that?
Does it say it's pre-treated with CalMag?

I'm using Botanicare blocks and have to add Calmag on the first soak,
then I add 1/2 strength nutes to the first water to condition the coco but I've never actually tested runoff from a fresh potting.
I sure will tomorrow, though.
Thanks.
