hey sweetie, all of my outdoor grows do what you are experiencing now. i think it may be in the genes, as i always used the same seeds, or seeds from a previous grow...

i recomend removing the dead leaves, and concentrating on keeping the rest of the plant happy. if they are dying a few at a time, i wouldn't worry to much. if they all turn color and start to die, then you have a problem.

mmho...

love, kp
