Purple Punch (?) Auto in Week 8: Brown/Yellow Leaves on Buds

[FreeJeff]

Hi, this auto is in the 8th week. Buds are growing nicely but the leaves are turning yellow and brown. My impression is that this plant's days are numbered. So here are my questions:
1. Should I be trimming the brown/ yellow leaves?
2. Until recently, I was giving in Bloombastic, but now just water. Is this correct?
3. How long should I wait before harvesting?

What's the breeders estimate for harvest and where's your loop to check trichomes? If you don't use a loop and want to guess wait for all those hairs to turn reddish orange and curl in or dry. It's normal for the plant to loose color and leaf deteriorates the buds drawing energy from them. I will go a week past the breeders harvest timeline but i also use a loop magnifier to see the colors of the trichomes bulb heads. Good Luck

Thanks! I'll try to get some better magnification. The breeder says 9 weeks from seed. I was worried that when the leaves turn brown I'll lose the trichomes.
