Thanks guys, appreciate the feedback and advice.
Ganzy, sometimes you can't predict how plants will react. From early on, the taller one displayed some sativa traits by it's taller, narrower appearance. The leaves were also more "finger-like" than the other plants. I took all the precautions to prevent stretching (i.e. lights within 2", etc.) but it stretched anyway during flowering. I am chalking that up to genetics.
The main cola on the taller plant is really swelling up. It's about 4" diameter and about 4" in length. As you can see in pic #1 above, the weight of that cola is forcing the stem to lean a little. Guesstimating, if I let it flower another 2-3 weeks, on the taller plant alone, I think I will harvest between 2- 2.5 oz wet. Not a lot but given how rough they've had it and it's bag seed, I'll be fine with 1 oz cured. If the middle and lower buds continue to swell the way they have, I'd say it'll be closer to 2.5 oz wet. The main cola alone looks like it's about 1/4 oz wet right now. The other 2 colas on the offshoots look to be around an 1/8 oz. Then there are the other buds all along the main stem that are just starting to fill out. If I harvested the entire plant right now, it'll be about 1.5 oz wet. Hopefully over the next week or so I'll be reporting back that I underestimated the potential and it's closer to 2.5 oz. That'll be sweet.
I haven't estimated yet on the smaller plants because I think that one is still earlier in it's flowering cycle. I am estimating that one probably needs another 3-4 weeks to reach it's full potential. I will say that the main stem on that plant is covered with buds. There is no visible stem at all, just buds.
I examined the trichs again this morning from the taller one and they appeared clear to me, another indicator that I have a ways to go.
43, I already have an order into Nirvana for Early Misty and Master Kush. I chose both for their potency (approx 19% if grown right) and ease of grow. EM is the strongest outdoor indica-dominant strain Nirvana carries and MK is a sativa dominant strain, which is what I want.
Smoker, I used GB early on in flowering but haven't since. I'll post an update again Friday or Monday.
