Simple Nutrients help needed

Hello, I've looked around and understand a lot of the different things people are saying about fertilizers but i'm not sure what and when these come into play.

I've planted seeds outdoors (in flowerpots) on a terrace (durban poison) less than a week ago. Planted with organic compost + potting soil + worm castings + perlite.

What time of fertilizer if any is needed throughout the process. any recommendations when i should introduce nutrients to these guys? How often? what ratios/etc ?

thanks!

Sounds like your plants will do just fine during the vegetative stage in your soil with nothing else. It's probably a good idea to start bloom nutes once flowering begins(every other watering). There are lots of brands to choose from. I think I'll be going with Foxfarm for my next grow. Last grow I used Advanced Nutrients with good results.

cool, thanks for the info. Since i wont have the different specific brands down here when it comes to flowering, is there some sort of specific ratio of the nutrients i should be looking for at that point?

No idea what you have access to, so just make sure the nutes are specificaly for flowering/bloom phase. There will usually be significantly less nitrogen than phosphorus and potassium.
