I know how you feel, i had to harvest one of my plants early.
and the other.... not doing so hot. most of her has just crumbled away.
i dont know whether high temps, low humididty or something else is the cause, but shes almost toast.
but dont fret! you still have the one plant!
i didnt get much off the one plant i harvested, but damn its nice.
and no doubt the buds you get off the one are gonna be awesome!
oh and since you only have one plant in there now, maybe remove a bulb or 2 to help with heat problems.
unless you have the heat problems completely under control now.
best of luck to ya!
