When should I flower?

Ok so i bought these clones from a club. they have been vegging for 24 days now. i was wondering when should i start flowering? and how much i should expect to yield? also do they look small for 24 days? pics below.

any were from now to two week depending on how much space you have

I say a week and a half now that I looked more. they are fine for 24 days old look nice. a little droopy. are you letting them dry out compleatly befor you water again?? you should

yeah i have been letting them dry out completely. i took the pics right before the light went out. they have been getting droopy every night like an hour or so before the light goes out. but they perk right back up in the morning. i guess they just know when its time to rest. anyone else have opinions on when i should flower?

Top them and let them grow for 1-2 more weeks, then flower. this will work great for you
