Baby's first grow

Now starting to swap over to flower right after this image was taken. They both got way too big for one 2x2' tent and began to overcrowd it badly. Luckily, I had another 2x2' tent, just without an inline fan so I'll probably need to grab one soon. Temps in the auxiliary tent sometimes scrape up to 82 degrees during the day. Otherwise, they seem to be doing OK with the main plant doing best. I'm not sure why the other has been struggling this whole time though. Growth is slowed, stems are purple, and it doesn't absorb much water from the looks of things. Roots are healthy on both though. I'll probably begin feeding some FF Tiger Bloom soon to see if it helps.
