looking good! maybe a little overwater on #2, leaves look ribbed and curled down at the tips, should go away in a few days if you dry it out a bit.
looks to me like you have about 7 nodes on #1-2 with the bottom nodes having the longest branches, @1in long? now, i use 600hps to veg not cfl so its hard for me to know if that cloning method i was telling you about would work and how long it would take to get them to the point where you could take the cuttings. ok, lets say i want to flower when my girls are about 12in. (w/ 600hps from 4" clone, @2 weeks for sativa and 3 weeks for indica) i would over veg for a few days to a week until they were @ 15" and this should grow those branches at the bottom nodes from @ 2-3" to 3-4" which will be much easer to make clones out of. then i would cut the main stock back to whichever node was at the 12" mark, use the top 3" as a cutting, then i would count down 4 nodes and keep those. this should leave me with maybe 3-4 or so branches at the bottom of the plant that should be @ 3-4" long. i would cut those off as close to the main stock as i could and clone them. i would then veg the plants for a few more days until they recover from the shock and i could see new growth and then i would flower them.
this is for big plants under lots of light, soooo....
if you do want to top, dont want to mother, and maybe just get a few cuttings, i would top now by removing the newest node, which right now is just the little nub at the top of the plant. at the point youre at now that should leave you with about 7 nodes, that after topping, should all start growing taller together trying to become the new main stock. hopefully in a week or 2 your bottom 1" branches will be 4-3" long and you could take 1-2 cuttings off each plant. then finish with more veg time until they recover, and then go to flower.
are you looking at me like this now? :wtf:

ps. i use GH nutes and love em. just de-boned my first light today, looks like im getting about 1.1# per 1000. bubba kush, turned purp, powder coated, @3 week veg, 8 week finish, topped, 9 per light, no co2.

pps. I WOULD NOT TURN OFF FOR LESS THAN 6 HRS IF YOU HAVE BEEN RUNNING 24HRS. use a flor or a flash light or something to keep light on them. you need to try to keep killing that hormone that causes them to flower. light is the only thing that kills it. even if you turn it on after youve done your business and shes in the shower. any little bit of light will help.
