This girl is on fire.
Her main bud is massive and fat. She has been in the main wardrobe for most of her life which shows in her Bud
I'm looking forward to seeing how she ends up at harvest.
@lukasbodo,
Without getting too technical this is what I know.
If the leaves are no longer green, then they can no longer photosynthesise, thus they are no use to the plant.
Alternative to this being that if they are dry but still green, then a bit of watering and they should be able to work again.
To answer your question when my leaves have yellowed I either trim down to the green parts, which can still photosynthesise or I completely chop off.
Hope this helps
