So are you using a single 600w lamp or 15cfl bulbs???

They do look ok for 26 days.... Like mentioned before, ideally you want to take clones from these before you put them into flower.... Clones are soooooooo much easier to deal with, OR you can keep one of these, from seed, as a mother.... Clones genetics usually get weaker and weaker from taking a clone from a clone from a clone froma clone from a clone from a clone, so I've read and heard but done know for sure....

It's up to you when you want to start flowering them.... You've already gone 26 days, once you flip to 12/12, add a minimum of 56 days til harvest....usually....
