Looks to be from what I see!
Yes it is. Shows best in pics 2 and 3.
Lots of new growth along with it also very early
How long will it take for buds to form?
Each plants different so it’s hard to say 4-8 should be an extreme scale from the soonest to longest aspect and anything goes in-between lol
Is it an autoflower or photo period?
Once you switch the light to a 12/12 schedule it will begin to flower. From there, ballpark, 10 -12 weeks
