People underestimate just how much a plants size increases when that 12/12 cycle hits. In the first 2 weeks Ive seen them double to triple in both height and width. Something to keep in mind.
It's hard to see from that one pic from above and I don't know what your grow is but... Looks like you might be in soil, are your containers directly on the floor? How much vertical space do you have? Is it in the closet?
