When to harvest?

I have some buds that look big and VERY ready. I wasn't planning on harvesting until Apr 4th, which would put it at 64 days. I don't have any yellow leaves yet, but the buds look very mature. Should your leaves always die off before harvest? I flushed and stared feeding them nothing but corn syrup on March 15th. I figured there should be some yellowing by now.

Try chocolate milk, that should yellow up them leaves in no time.

Go by the color of your trics if an photo plant, amber for couch lock, clear for energy etc etc
pr it an auto use fading fan leaves and trics as an indication
