1) Nobody in the world can tell you what that strain is,nobody!
2) Looks like a sativa/indica hybrid...could be anwhere from an 8/9 week strain or a 10/12 week strain.So if you're 3.5 weeks into flowering,you could have anywhere between 4.5 weeks to 8.5 weeks left.The only way to know when to harvest is get a 60x to 100x scope and check trichomes around week 7 and 8.Clear trichomes are immature,cloudy/milky trichomes are mature,and amber trichomes are degrading THC.Try to harvest when 90% of the trichomes are milky/cloudy and 10% are clear or amber.
3) Nobody on earth can answer that question and if you've soent anytime doing your homework and reading the other threads asking that same question,you'd know that nobody can tell you what you'll yield...PERIOD!
When it comes to yield it us about all of these factors/variables...
1) Genetics
2) Dialed environment (proper lighting,air temperatures,ventilation,humidity,watering/feeding/nute strength/pH,growing method).
3) Grower skill level.
