Yep - that’s what I thought. My mel’s mix has done better in subsequent years with growing winter rye or wheat and turning under as well as adding plenty of compost each year.
It might be worth a try to add some more compost as a side dressing, maybe even some bone meal, blood meal, and throw on a few banana peels and crushed egg shells.
Have you tried any water soluable fertilizers?
I think I am going to turn it over, add some compost and try again. Sad thing is everything is growing so nice, if only it would bear veggies.
Maybe add a few different kinds of compost.
