I started seeing buds forming on mine two weeks ago but they seem like they are further along then two weeks. What’s your guys methods for knowing the weeks and when to flush? They say 8 week flowing time so I find it hard to believe they still have six weeks left.
Don't start worrying about the flush quite yet. Depending on if your doing salts or Organic, you might want to keep your microbles, and continue to feed the plant, put on more, size, and far more weight. Might be surprised how much they will continue to swell with good care. I would consider maybe getting some humics/fluvics, or doing a nice tea of some type. Maybe add a bit of bat guano, or whatever. You want to start feeing the plant what it needs to increase terpene production, (right now) and nutrients to catalyze increased alkaloid production in the plant. Even on a budget: fish bones, or bone meal would work... maybe some wood ash (if this is an organic grow). There are so many options. You might already have one. What's your regime? Is this a premix soil?
The longer the pant feeds, the riper it becomes. That biggest mistake I see with new growers is jumping the gun to harvest. Patience is a big virtue in growing, and guiding things up to the right moment helps bigtime.
Most of your heavy ripening and oil production happens in the very last days. Then like 79 says, you let it coast the last week, and letting it cannibalize itself to the finish line.
