Problema Calcio DWC

if it's older leaves it can be related to PH and excess.. Newer leaves tend to show deficiency and PH as well. The foliage will not fix itself.. I think your expecting to "find" a solution that will get those leaves back in good shape.. doesn't really work like that with plants.. Generally she's gonna abandon older leaves by her very nature.. High foliage plants tend to have no issues shedding leaves (think autumn and how a ton of tress shed their leaves). Your excess calcium can cause the problem.. And if you stop feeding the excess it will not change the look of the older foliage.. It will change the look of the new foliage. Your nutrients being in check has a lot to do with growth.. If your plant is growing strong that's a good sign.. If she seems to be slowing down in growth that can be a "bad" sign given the timing of course.. Cannabis doesn't go "stagnant" it doesn't spend days making roots.. If everything is correct plants will grow.. Period.
