No problems True.
The pH problem was when testing run off it was 5.3 but going in at 6.5 this means my soil was somewhere around 4!!!!!!
I thought putting them in the bath would up the pH of the soil as my tap water is around 8.
But I was wrong, the way to fix low soil pH would appear the be with Dolomite Lime.
I put a a table spoon on top of the soil and 'raked' it in the top layer with a dinner fork.
Next water I did very slow as they are still quite wet from the bath. Tested the run off and its coming out at 6.1 this morning. So heading up nicely.
Cheers for looking man.
Any more Q's, just ask away.
