1.) I would say once you see them doing well maybe two nodes then transplant them, be gentle, in vegetative growth the roots grow 3x as fast as the plant

2.) I don't know if Fox Farm Ocean Forest is organic or not, but it's widely used with great success

3.) Lighting is all preference...for Vegging you can either go 18/6 or 24/0...try it and see which one works best for you, make sure your light is close enough to the plant to prevent stretching, but not burn it

4.) idk what TLS is...

5.) Vegging vs. Flowering time is all preference as well. Vegging longer means you will end up with a larger plant and more yield, some people grow 12/12 from seed...it's up to you, how big do you want it

6.) It takes a couple weeks into flower usually...from what I've seen

You could have figured that out with enough reading here. It's not ALL in the FAQs...

Good luck :thumbsup:
