Stretch and enough space??

OK so I am just over a week from when I flipped to flower. They haven't seemed to of shot up any yet really but looks to be showing signs of bud areas and I'm hoping I'm doing good. My questions are do you think I have enough room in there for all 3. My original plan was 2 but become attached to all of them and the one I did consider dumping I would like to see it through with now. Any other comments on set up as I am pretty new to led and going it alone this time. 2 critical kush and 1 incredible bulk in plant magic plus soil and there brand nutes oh at. 6 ish.

You should be fine on space in there

Both those strains stretch quite a bit but from the looks of things you should be ok. What is the plant height now and how much head space do you currently have?
