Welcome. I think we would need some basic info like where you are located and are you growing in the ground or in containers etc. As far as fertilizer it depends on the size of your plants and whether they are in ground or pots. Any fertilizer will work, but the right application rate needs to be followed. A balanced fertilizer is an easy solution, such a 10/10/10 or 13/13/13. An ideal fertilizer would be a 2-1-3 NPK ratio, but those are expensive and the cheaper balanced will work just fine. You can also just amend your soil with compost, manure etc and grow organic.
