How are my plants looking?

4th day in to flowering, Day 35 of life(from seedling). I just put these plants in to flowering, trying to sex them so i can catch any unfaithfuls early on. I'm keeping the grow very short in height. Are my plants experience a nitrogen deficiency or are they just adjusting to the 12/12 lighting schedule? I've just switched them from 24/7 to 12/12 and i would like to know whether they need some extra nitrogen in to their feeding schedule or this is normal. Any help would be great, thanks.

looks good to me why do you think there might be a nitrogen deficiency?

i dont see anything wrong with you plants m8.

Those plants look fine.

Thanks guys, i was just worried because of the lighter yellow leaves, but they eventually turned darker. Thanks for the help anyways.
