First Clone to Bloom Grow

Had to leave for a week and so I shut off the fans to reduce the number of things that could catch on fire. As a result it got a little extra damp in the chamber, but nothing too bad. Both plants have some great buds coming along; the weird thing is that one is looking super healthy all around, and the other has leaves that are starting to yellow/brown on the edges. All conditions between the two are exactly the same... I plan to just keep an eye on it for now.
