pretty leaf on that last one, nice sawblade like a skunk leaf. did you ever try a tiny bit of hydrogen peroxide?. i dunno if that could be magnesium..... lots of things look similar to that. but it seems to be outgrowing it it could be dropping it because of past stress and past it now... or could be something new. the new leaf color and vigor look good, could probably feed even a tiny bit more. not a lot more but the leaves can go even more blue....
