Any Youtube or twitchtv channels that focus on teaching people how to apply jungle strategies?

I want to learn proper jungle strategies. I noticed that I know very little about how to press my advantage or how to recover from falling behind. I barely know who to gank or when except for ganking lanes that are really pushed or low hp. I don't know jack **** about invading the opponent other than waiting for him at their buff with a duelist jungler and pray that nobody knows I'm there. I don't know how to keep track of my enemy jungler. I once hit platinum for certain strategies that I used to apply repeatedly but got stuck at Plat V because those strategies relied on punishing really bad mistakes that people made at low elo. Furthermore, I came back during the previous patch after a two year break and even forgot most of those strategies. I could probaby binge game my way up again and learn purely from mistakes or lucky successes like I did before but that only got me to Plat V and that was probably because I got lucky in my Promos. I'm currently low silver and struggle to win matches even when I get really fed and ahead because most of the time I either neglect lanes when they need me the most (for example: bottom when they're pushed but I 'm too far away and they end up pushing them back or kill them and securing dragon). The only channel I know of is stonewall008 and while he is very helpful, his commentary is all over the place so I find it hard to know WHY he does the things he does. His low elo videos have some golden nuggets here and there but those only helped me for very specific situations. What other channels can I watch that focuses on jungle strategies?

TL;DR: I want to learn jungle strategies so that I can finally know when to press my advantage and how to recover from set-backs. What are good Youtube channels that focus on teaching jungle strategies to jungle players?
