Thanks shadylane, I'll go pick up some fish emulsion or blood meal stuff soon-- I really was sure that coffee grounds have a ton of nitrogen, lots of people say/write that....
I never ever see slugs or snails around not just my garden, but on our property and in the neighborhood in general. Honestly, the last time I saw a mollusk was last summer in Europe... wow, crazy. As for cutworms, I haven't seen any cut stems-- the cut ones are my thinning-- only those holes in the leaves.
I remember I had similar holes in my radish leaves last year, but the radishes grew just fine anyways so I didn't bother with it. I read that spraying with a tea made from garlic/onion skin peels repels insects, so I will try that.
Another problem with the radishes, I planted them Nov. 11th, so 21 days ago, and the roots are still not bulbing at all. They are just thin and long. I know, because I can see that they are just stems, and also I ripped out a few of the ones that were looking the worst today-- perfect long, red stem that goes down deep with nice roots at the end, but absolutely no actual "radish".
It is so weird, because last year(not even a full year actually, two seasons ago) my radishes grew so very well. ALL of them were nice and firm and fat. My tomatoes, strawberries, and sunflowers also did very well, and this time around everything is doing bad.
Funny thing, I have lettuce growing in a container right next to the garden and it is growing very, very well- so I think it is a soil-nutrient issue, and not a sun/water/pest/disease problem. Same type of lettuce, same planting day.
As for the spinach, I'm not sure. It seems pretty OK, it just seems as though it has stopped growing. It has been at that height for days now, with no changes, I'm not sure why. It is very frustrating, I really hope all of this work won't go to waste....
