has it got too dry or had any heat stress ?
Some of the lower leaf looks like the plant may have got dry or hot ?
Stress can cause seedy weed and so will too much heat, too much heat can also give you very loose untight buds
Have you got good airflow ?
what size hps have you got and how close to it are the plants ?
Also where did you get the seeds from ?
This is my first grow (well I guess second but first was just bag seed under cfl as an experiment and turned out male). So after kinda seeing how easy the bag seed was to grow I got "legitimate" genetics (Midweek Song - actually from their personal seed bank as well) and it spiraled from their so now I've got a 4"x2" tent with a 400W HPS in an 8 inch cool tube:

It's got a 6 inch inline fan (I think 150 CFM?) pushing the heat to the left in this picture, and then I also have the end of the ducting kinda jankily duct taped to the fan of an air filter (pretty high powered) for some extra kick. Then Idk if you can see it in that picture but in the back right corner I've got an oscillating fan going to stir up the air in there. Oh and also a big old fan (like the common ones from Walmart or whatever that are square) that's "sucking" air out through one of the 3 bottom vents (all are open).
Anyways, sorry, I had a big test and kinda took a lot of Adderall today if you can't tell so this is probly way too detailed.
But like I said before this is my first grow. So I was unaware of the different flower stretch potentials of various strains. Then I found myself in the position where I see my plants getting way taller than I expected after switched to flower lol. And in particular, my misty plant stretched a fuck ton more than the rest. So I suppose it was quite close to the light. And I can't / couldn't really move it up any further.
I actually figured this could be a possibility of what's causing it as well yesterday! I was all worried and babying them, so I did some surgery on Misty by just tying the branches in all kinds of weird positions so that the buds are not as close to the light. Misty is on the left in the picture.
One branch in particular is now side ways in the back stretching like almost all the way over lol.
Short plant my ass MWS...
SO. What I've been seeing in terms of temperature wise is it's about 80 MAX with average of about 78 probably where the colas of GSC/ NYCD are. These are about 18 to 14 inches away from the bulb. I've been told that THAT is too close and I've been told that that is prefect by people. The temp may be a bit on the hot side for flowering, but what I'm seeing is that GSC and NYC Diesel already have some really dense buds forming... and there's still a good month at least (probly more) of flowering for them.
However, with Misty and it's ridiculous stretch - at one point before "surgery" I had measured a couple of her colas being as close as 7 inches from the glass, though the bulb is on the other side of the tube so really it was really like 12 13 inches away from the bulb, BUT it was still hotter up there (the thermometer was a bit lower). Id guess it could be like as much as 83 to 84 farenheit. So maybe that could be what caused this... but again I wasnt sure. The leaves had been doing some funky shit like curling and then some were yellowing but I figured maybe it's just bc it's getting closer to flower. But now maybe I guess it's heat stress? Could that be causing the skimpy buds too?
As for the dryness: it's winter where I am and has been cold and DRY for months. In veg I had a humidifier going just about 24 7 to keep that up to acceptable levels. But I'd read that when flowering you want the humidity kept very low to avoid the possibility of moldy buds, so I turned it off. Now humidity tends to be around 20 to 25 percent usually. Occasionally I'll mist a bit with a very low concentrate nute solution if it gets to be like below 20.
The other plants seem to dig the set up at least! I've got clones rooting for round 2: Monster cropping, that I took like a week ago, but now I'm thinking maybe I should take some more GSC and NYCD clones and pitch the Misty cuz this is frustrating and I don't want my other plants suffering as a result!
Supposedly when i started the description of this plant misty said it was really easy to grow. According to reviews I'd likely have much more trouble with growing NYC Diesel. So I figured the opposite would be happening right now. But here we are with NYC Diesel strangely being the strongest hardiest plant by far... and misty is... not misty.
