When Should I Flower?

Sixth node! Wow thats high but it dont matter. In future you can top as low as the third node on a good growing plant or fourth node is what people say is rule of thumb. Yer if plant is healthy you will still get good growth if switch to 12/12 in like a week. See how much mine grew after i topped it in the space of two weeks 12/12 which is how long mine take to start to properly flower, after that the buds only grow like a few inches higher.
Yer let the chutes fill out a bit and try let the ones from the lower internodes grow up to the light a bit whilst training the top ones sideways, that way you can get good growth before flowering and stick within your height limits. Post pics dude so we can just simply tell you and try take some of the guess work out of it for you. If not then you should be able to judge when they need to flower and keep the height down.

I have two plants that are significantly bigger than all my other plants and Im having trouble keeping the lights low enough to the smaller plants without burning the big ones. I figure I should just flower the bigger ones and get them out of my grow area cause I don't wanna murder them. Can I flower anytime or is there a specific age? Please give advice.

if its a clone its an adult plant
but the better the root system the better the yield!!!!!

I'll be at work till 6am central time. And when I get home ill post pics.

Ok dude, ill see em tomorrow night. Peace

The first two pictures (307,30 are they topped plant we were talking about. The 3rd is a plant that has seemed to stop growing up and is just a short little bush. Don't really know what's going on. The 4th picture is my other topped plant that is a lot smaller. And the last two pictures you can see the stems are purple. Doors this mean purple strain? I've heard that, just wanna clarify.

Plants look ok, i would bend the top 2 chutes sorry shoots under the leaves nest to them or tie them so they grow sideways and let the two shoots under them grow up to the same height, flower in one week if you are trying to keep them short. As for the stunted plant idk, looks green and healthy, are all the roots getting enough water in that big pot? Still it looks ok.

Purple stems and stalks do not mean you got the purple strain, sorry, no matter what anyone says purple stalks and stems should be green and to me sybolise a slight pH problem or ferts issue, either way marijuana plants should not be purple. Some seem to think it is ok, i did till it dissapeared one day when i adjusted my pH and ferts. Marijuana plants stems and stalks should be green so there is room for improvement, that said i am impressed good work. Peace

Thanks a lot for the info.rep+
