Well Bunique if your growing outdoors and only a few plants its less likely its Powder Mold, However it may be signs of a deficiency... although i have a book that has a picture of an aphid problemed plant, and it looks like that... Kinda white spotish around the aphid's area... like maybe there poop?
It looks pretty nice though, but sure looks like a lot of leaves from the main cola,, i just started my ST MOM, and i have 1 in flower right now to see what i can expect.... All those leaves are telling me that this is going to be a nightmare strain to trim.... Right? I may want to look for another MOM for future generations..and do away with this simply because of the trim time....
