Should I flower now?

She is 8 1/2 inches tall and bushy as heck! I topped her at about 4 1/2 inches. She's always been a bushy plant. She grows outwards more than she does upwards. She is 1 month and 3 weeks old. She is Lemon Kush. I started her from a excellent seed. I have her under 4 cfls and 1 led UFO. Here she is!!!

How much room do you have? Allow for:

a) the plant to triple in size
b) plenty of space for airflow

If you calculate that and still have room to go, and are not in a rush for the produce, I would wait. No reason to not maximize the yield the plant is capable of.

The bigger you let it get during Veg, the More your yeild will be in the end.
How far away are your lights? It just seems a bit small for the amount of time in Veg.
Go for it whenever you want. Expect 8 weeks of flowering time after the switch.
Love the Strain!

Yeah the longer you leave them in veg the bigger/more yield you will generally have.
They also say the plant usually doubles sometimes triples in size once you switch to flower so if height is an factor then keep that in mind

yes i would if i was you because if you are only using 3 clf and 1 ufo the bigger the plant the less light penetration you will have so if its too big only the tops will get enough light. clf will only penetrat 4 to 6 in past the top of the plant

8 nodes you can flower. Beyond that its how big you want to go

You could flower sooner but what's the point? 3 months for a few bowls?

It is IMO based on height, space, and light. Some of my strains will triple in height and many times have been caught off guard, running out of room. Also if only running CFL's light penetration could be an issue if you have no room to train. I'm typically on the verge of running out so that makes the decision rather easy! Get ur done lol.

Like everyone said, don't underestimate the stretch in flower! At 8.5" I bet that lemon og actually stretches to almost 30". That being said, it's not a big yielder. If you flower now you'd be lucky to pull more then an once off the plant, esp. with cfl/led. If you have the room I would veg longer and plan for a trippling in size.
