I have a Sativa dominant "massive midget" auto going and have having trouble telling when to harvest. The plant is no midget, and instead of harvesting in 8 weeks, as Heavyweight seeds suggested, it is currently on day 89. If I harvested today, I figure I would get at least 4 oz dry and this is under a 400 hps shared with three other plants. I would estimate only 50% of the hairs are brown on this plant. When scoped one observes the occasional amber head, but the rest run clear, no milky heads. I would estimate 75% of my leaves are yellowish and what worries me is that the margins of my calyxs' are turning pale yellow on many buds...I am tempted to pull now because of this....any thoughts?
