I would suggest a granular fertiliser for veg. I use fish blood and bone. Things like tomatoes in pots, grow bags etc can be fed with liquid fertilisers and I like seaweed for this.
I'm not keen on high fertiliser rates. Organic fertilisers are generally slower acting and help " feed" the soil too. In my opinion, artificial fertilisers are often harsh and too powerful producing soft, lush, more-easily attracted to pests produce.
Soils with high humus levels but little fertiliser content can still produce decent crops. Poor soils with masses of fertiliser added produce poor crops.
If your soil has plenty of compost added a good organic moderate-level fertiliser is all you need
