Its not too late to take clones my man (in fact its the perfect time). If it were me, I would chop some of those little bottom branches out and root them, since they will end up being loose popcorn anyway under that 250 HPS. The cuts will need to revert, but when they do, they will be bushy as F**, since new growth comes out of each bud site. Some people will say that this messes with your genetics, but I have been doing it on the saime strain for a year, and havent seen a difference in quality (if anything the quality has gone up as I "mastered the strain").
I know you are reluctant due to space issues, but a little dome and a single flourescent is roughly 2' x 1' x 1'... YOU DO HAVE THE SPACE SOMEWHERE. Its not worth kicking yourself when you have harvested, and you have something special. Remeber, all seeds are different, even if they are from the same mommy and daddy. You may have the next big thing there and it would be a shame to lose it. The cost for a dome tray and light would be less than 40 bucks. Get on it.
PS... Looks like you fixed your claw problem. Bump the nutes up slightly next week. Are you using tap water? if yes, adjust pH after you add the silica. Use the silica through week 7. Is good for them, and will help keep pm at bay when winter starts setting in.
If you are using RO, usually your pH will need to come up a little after adding nutes. This is when I use silica as a natural ph up.
As far as your closet goes: Take the door off, attach a piece of
panda film over the door opening with some tape, and then you can add ventilation through holes in the panda. Ventilalion is the most critical thing in your set up. You want air moving all the time.
Looking proper in there strange. Keep up the good "work"...
