Help palnts flowering to early !!

Hello All, I'm growing 2 Afghan Kush which are about 6 weeks old and on 18 hours of light a day. When i checked on them this morning it looks like they have started to flower ! How do i stop this ? should i put them on 20 hours ? I want them to grow a bit bigger b4 i put them into flower.

Hello me again, I think what i'm going to do is put them upto 20 hours of light & 4 hours off & hope this will stop the flowering and start them growing a bit more.

What you are probably seeing is preflowers, so they are probably mature and could flower if you wanted.

what are these preflowers, mine have the two white pistils coming out of a very small calyx at where the leaf and branch start on the main stem at the very top of the plant. Would i be able to keep them on 18/6 for another 6 - 8 weeks then put them in flower, coz there small at the moment want them to be bigger b4 i put them into 12/12, thanks for replying cph.

From what I've heard unless u go under 14 hours of light they won't really start to flower. I have left mine in veg for 6 weeks and have the same thing, it shouldn't go any further.
How big are they? Any pics?

those 2 white pistols are the preflowers this is the earliest signs of the sex your plant will be and like the last poster said shows that the plant is mature and ready for bud time. Next you'll see clumps of pistols growing from the tip top of the plant. Do you have pics for us to see? When they begin to flower they will double to triple in size especially if your change the lighting schedule to 12 on and 12 off. Pure indica plants often mature sooner than sativas or sativa/indica mixes.

Let them flower away, seems like that is what they want to do. luck to ya

Thanks for the reply's cph and bra smith, going to keep them on 18/6 for another 6-8 weeks hopefully there be bigger then and then i put them in 12/12, definately preflowers, could'nt get a picture close enough to show you the preflowers. Here's a pic of how big one is. Thanks for your help.

Your plant is real good lookin, nice and healthy, good job. Do you plan on taking her outdoors later or continuing it as an indoor grow?
