Northen Lights Auto 4x / Southern Europe

Week 5 in veg. Good weather overall, major development in 2 of the plants, like i said in the last week, i'm kinda giving up on the other two, they didn't develop and they are getting brown spots and i don't know what to do. i think i have something like two weeks before flower and this crop will be kinda shitty that's it guys, good smokes everyone.
