yes do not harvest you will get a lot more bud and it will get ALOT more potent also that purple strain kinda looks like Purple Passion a very nice dominant sativa strain and the light green looks like a kush varieity with a dominant indica strain what this means is youve got two different speiceis of cannabis the sativa will give you a light fuzzy euphoric almost giggly high :clap: and the indica will give a down very relaxed "couchlock" high :stoned:
