Get them out of the same pots before there roots get together and you have a mess on ur hands. Replant both of them deeper. Cover the stem up to the bottom set of leaves and the stretching should stop. What soil are you using? Looks like you need some perlite.
I'm take you have more and another pot?? Getting them put of the same pots is really what you need to do. The plants will more then likely both out grow the pot. And you don't want the roots to tangle together and hurt them. Especially if you become root bound and your already in flower. Force alot of stress. Then might hermie. Then you got alot of seeds. But.. why did you post this in the crop king seed forum? I don't recall them selling blue dream.
