Master kush questions

hey all . im on my first grow and i have a couple questions about my strain. its master kush from nirvana. was just wondering when they start putting on weight so to speak. im only 10 days into flower so i dont expect it to be now , but i would like a time frame to judge my grow by. i have preflowers on all four plants so im doing something right lol. anyones info with experience with this strain would be great.

this was mine at 7 weeks be patient bro[video=youtube_share;ucY5sVB3hMA]http://youtu.be/ucY5sVB3hMA[/video]

Oh this was from two years ago, but I cut her down at around 65 days
