hey, those some nice healthy-lookin plants ya got there. what do you mean by tabacoo smoke? like are you blowing your smoke towards the plants?
Do NOT smoke tobacco near your babes. The smoke can transmit tobacco mosaic virus, which will kill your ladies.
Sorry for so many questions, but these are 3 months old give or take. Shouldn't they be showing their sex by now?
the sex of the plant depends on how manny hours of light you have on the plant. it looks like that thing you circled on your picture is a new branch that is emerging out of your plant. meining your plant is getting more bushy. !!!!!!!! i dont know if you have but you should try and read a indoor grow guide if you dont under stand the 12/12 or 18/6 light cycles. it will answer a lot of your questins (instead of figuring out from trail and error)
Those are present on both males and females. SpanishFlys post about sexing is an EXCELLENT guide. Heres another one from overgrow faq: http://www.drugs-forum.com/growfaq/1250.htm AND http://www.drugs-forum.com/growfaq/1037.htm Good Luck. - Vince
You can make any plant flower as long as it's a bit mature. You could prolly make it flower and get bud from it, but why not let it grow so you get more? If you put them on 12/12 already, dont expect a ton of bud, let them get a little bigger and more mature, then switch. Just my opinion. Good Luck! - Vince
