Hey SuKa, just wanted to let you know I subbed up.
But dude, I really think you worry too much. Your plants look fine!! Great actually. I agree with the statements from K and Shag, regarding optimum ph in soil, but to be honest, I really dont see any deficiency....All I saw is what somebody said a page back, possibly a hot spot of nutes in the soil, and a little leaf burn. At this stage in growth, as long as you see healthy new leaves continuing to grow, then eff that leaf! I'm fairly new to growing myself, but one thing I learned right away, is that sometimes we panic, and "over-love" our plants, in an attempt to "bring them back", when, really, they may have just hit a bump in the road, and aren't in any real danger....So with all the switching, and changing, disturbing and so on, the plants end up MORE stressed than they would have been had we left them be....
Sorry didn't mean to ramble, just my two cents....Anyway, things look good over here brotha! +reps for starting another grow inspite of your males a while back!
