Over feeding can make brassicas (in particular) prone to disease, earlypea, especially at this time of year.... :-\
Re-reading it Earlypea, and if you have had the dry September we've had, I would suggest dry at the roots, that would encourage mildew on the spinach and whitefly on the brassicas which would create conditions for the mould to flourish... I'd dig in more muck for these crops to improve the moisture holding of the soil, which it sounds like your neighbours have been doing over the years.. :-\
Do I come across as that old then.... :-[
