Final Flush Question

When the leaves begin to yellow during flowering, consuming the remaining nitrogen from the plant, is this a sign the plant is nearing its end and time for the final two week flush?

I do not have any idea when they began flowering, so I'm going by the hairs and trics more than anything. Any help appreciated.

It depends upon how ripe the crop is. If your nugs are ready to harvest than the leaves may very well yellow as the plant completes it's life cycle. However if the buds are still young you should troubleshoot that issue.

if the leaves are yellowing and you think you're nearing the end you're only choice really is to flush... can't add nutes unless you want to risk having harsh smoke

do the nugs feel firm and full? are the glands at the nodes swollen big and round? i bet if you threw up a picture fdd or somebody could tell you in 7 or less pixels if it's ready or not
