First Timer: Lithium OG Kush Autoflower

I would say this week is where things started to get a little hairy. One of the plants has started to develop rust discoloration and a not-so-natural looking fade. Maybe stressed after my vacation last week, but I decide to push through to the end without changing anything. The upper colas now, in addition to bleached tips, are starting to show heat stress on the leaves. I take no action and decide to wait and see. Also keeping a close eye out for any signs of pest or 'nanners. Two more weeks...
