Hi Mark, yes I wonder whatever they did.
I had a rely to my complaint saying
“We have had just one other query on the same batch regards slow growth on brassicas.
The analysis results show a slightly lower P.H than normal and a very slightly lower available nitrogen level.
It’s the only thing that really appears any different. It would be interesting to try a sprinkling of lime on the compost to see if that made any difference, and maybe some extra nitrogen in another sample.”
So it’s a puzzle in that sense, because something is impeding growth.
