Flowering (3/4weeks) no buds/yellow leaves

[LIP]

Dont pull the leaves off! Let them die off if their going to. THey're getting all the energy to form buds. Leave them well alone!

It must be a long flowering sativa.

why? what happens if there is light leakage?

The reason you don't want any light leakage, is because the hormones in the plant that cause it to flower are doing their work during the 12 hour off period.

Whenever the plant gets any light, these hormones stop reacting.

Even long flowering sativa's have signs of flowering in 2 weeks time. I'm guessing a low night temp (slows down flowering) or light leaking in.
