closet grow, running 400w MH as well as 2 24'' fluorescents, one warm one cool. they are vegging, and have been for about 3 months. they've been through a lot. both in regular potting soil, using all-in-one miracle grow (both were bag seed, experimental first grow outside turned into closet set up for future ebb and flow, these are just guinea pigs but i want them to flower so im trying to keep them healthy, obviously)
here's the problem, the larger fan leaves have these greyish, almost translucent spots which have been getting worse to crispy then flaking off, the worse spots are slightly brown. the spots are pretty random, some on the edges some in the center of the leaves. the smaller leaves (towards the top of the plant) look like they are about to go through the same thing, starting out as a green discoloration (more of a lighter green around the edges of the leaves, no holes just kind of splotchy off-color green). i watched the larger fan leaves go through the same thing but now they are just crumbly and crispy. they aren't brown spots like a mg problem, but they don't look completely like a copper or potassium problem either.
