Yo Ethan,
I have posted this on the list as I think it is of interest to
all growers. This is what a laboratory over here has put down as a guideline
level. I don't agree personaly with it all, especialy the PH. I would like
the list to let me know what their guideline level would be.
Thanks,
Alun

phosphorus...71 ppm
