the two tropical fruit guys i watch religiously are flying fox fruit and florida natural farming. fnf, on the other hand, doesn't have quite the same charm, but i love that he's always reading relevant scholarly papers. and his garden is the closest to my dream garden.
I used to follow fnf but haven't visited in a long time. I don't think he gets around much because he hasn't compared his mango trees to those of others. Mango is about the easiest fruit to grow in Florida but his trees look highly stressed with very small twisted leaves showing deficiencies. Many of the leaves are growing in strange horizontal angles. He is getting some flowers but admits to poor fruit set. Anyone growing mango will quickly see something is wrong, but he seems blinded to it. Ive tried before to make productive comments but he is recalcitrant and shuns people just like he left this forum.
To see what I mean have a look at his latest video and compare to your own mango trees. I wish he would be open to discussion but that never happened.

I appreciate people who experiment like FnF and share their findings, but it seems many don't actually want to discuss and accept their methods aren't as effective. To be able to stand behind your ideas and principles is great, to a point. I have had many theories about fruit tree growing which have been thoroughly disproven and I accept I was wrong to the best of my ability.
YouTube is much like any other social media. The more likes, follows, shares and comments you get, the further your video goes. It will also take you further and further down the rabbit hole of whatever content you interact with. YouTubers are often motivated by this rather than any core principle or scientific knowledge. If their goofy video about soil health gets 1mn views, guess what, you're going to see another... And another... And another.
Maybe you've seen the "Biggest Little Farm" movie which was received with much fanfare. They spin a story about how their little farm has been totally profitable and how they're living well off all these permaculture based techniques... But some folks peeled back the layers and it was much the same as, "With a small loan of $1mn dollars, I was able to build an empire." They are consistently infused with substantial money from outside sources (family, movie, etc) and the farm does not pay the bills.
We have one of the largest corn farming industries in the world in the US, but it is largely made possible through heavy government subsidy. Profitably farming is crazy impressive, and rare. Kudos to anyone who can pull it off.
I should probably be making some videos about my garden and shit soil, which is ancient beach sand. I've gone from zero loam to about 3" over the last few years, who knows, maybe I'll make it big on YouTube!
