Not sure when to harvest?

[happymedicine]

Hey, Guys. So I have a question that needs a somewhat precise answer (or as specific to this situation as possible). I have two strains growing, a Grandaddy Purple@ 30" and a Bubble [email protected]' I was just wondering whether or not it is getting close to harvest. i live on the central coast of california and have these growing in my backyard. I thought these strains would not be ready until october, bu they are exhibiting some signs of harvest coming in a few weeks (based on what I have read).

The Plants

1. Bubbleberry has about 5-10% amber trichomes (some still clear and majority are milky) and about 20% red hairs (majority are still white/yellow hue). About half of the fan leaves are yellowing, 10% have wilted and needed to be removed/fallen off (mainly on the lower portion of the plant, but some on upper portion). The colas have packed on some decently resinous flowers, but still seem a bit leafy to me.

2. GDP is exhibiting similar attributes to the Bubble berry), but all of the fan leaves are still dark green (unlike the Bubble Berry).

On both plants, not all the buds are exhibiting these traits. Some are still looking very much like they are in "development stage of flowering.


My Questions

1. I am wondering if I need to start flushing these in order to ready the plants for harvest in a couple weeks?

2. Should I harvest them a bud/branch at a time?

3. Am I jumping the gun a bit?

4. How much longer would someone estimate I have until harvest?

I am sorry if these are rudimentary questions, but this s my first grow, and I just want to make some good smoke. If they are close to being ready< I need to get to constructing a drying cabinet.

Thanks, Guys

If you wait too late, the trichromes will turn brown and start to fall over. Early harvest is head high, late harvest is usually couch-lock. I would wait until 50% of the trichromes are milky white and 50% are amber to harvest. It looks like the plant with the yellow leaves will be ready to harvest first. I would stop feeding the plant nutrients and flush them two weeks before you plan to harvest. It is hard to tell how much time you should wait before you start to flush though. When you cut them down. I would cut a branches at a time. Before you hang them to dry, remove all of the water and fan leaves.
