I noticed some spots on the two lower leaves of one of the plants. I browsed thru the forums and read a bit, but I still have no idea whether it's because of nute defficiency or bugs or tinfoil. Pics posted (1st and 2nd), does anyone have a clue ?

3rd pic is of another plant, notice the eastern leaf with some shreddage there :P Dont think its anything serious but just posting to be sure.

Cheers!
