I can see that the plants are flowering, the old fans seem to be getting discarded as they are not a priority for a flowering plant... apart from that i dont see any issues worth getting all hot and bothered about, in fact, the plants look to be in great shape and pretty healthy, weed is a tough plant, it grows in some pretty inhospitable places...
Thats my penniesworth.
But I am sure there are people here with a better, more informed response than mine.
