As someone who has just started his journey into Blockchain development, here's resources that helped me on my journey. I'd like to note though that I have a background in coding in Java, C++, and Python already although I would say I'm average in my coding experience. As everyone said, it would be best to learn a little bit of coding so you can at least understand how to read code and know the fundamentals of how to write it. Once you get there, definitely check these resources out.

http://consensys.github.io/developers/articles/101-noob-intro/ (A good read to start your journey into developing)

https://www.youtube.com/playlist?list=PLH4m2oS2ratdoHFEkGvwvd7TkeTv4sa7Z (A free set of tutorial videos on YouTube that goes over smart contracts and how to write your own DApp)

https://app.pluralsight.com/library/courses/blockchain-fundamentals/table-of-contents (Sign up for their free 10 day or 200-minute trial. You can easily watch this whole course within the trial, just be careful in rewinding and take your time.)

https://www.coursera.org/learn/cryptocurrency (An online course that goes into the technical details of Bitcoin and Cryptocurrency. Very detailed and works like an online class with assignments that need to be submitted at certain times.)

I've also bought a bunch of Udemy courses for $10 each that I haven't gotten to yet. If you want to buy these courses for that price, use the coupon TIENDEO10 to get them for only $10. I don't know how long the coupon will last so if you really want an extra source to teach you the material, I recommend to buy them quick as these courses can go up to $100+. This is without knowing how often these courses actually go on sale however.
