I've not found a veg which doesn't like it.
You can make a brew with it and use as a liquid feed, I feed all my stuff in GH with it.
I put it in the bottom of bean, spud and sweet corn trenches before planting.
I've used it as a mulch in the top of chillies, pepper and Tom pots this year.
It dries well and can be scrunched up to use as a feed around plants too.
Used as a spray and mixed with garlic and a little olive oil, I use it sprayed on black/green fly. The seaweed part of the mix is good for the leaves.
Seaweed is great stuff, not really a fertilizer, more of a plant tonic and health booster.I use it on everything from seedlings to mature plants both as a spray and seaweed meal to add to the soil
