Thanks for the advice and link! She's got a lot of interior buds and I've got some side lights on her to get light to them.I imagine the plant has grown and shaded out the lower leaves which is why they are turning yellow. Maybe try to open the plant up by tying some branches down so that it looks like a star from above. Let some light into the interior and the smaller buds in the cleft of the branches and trunk will be able to grow.
look at this link:
