some nice colas stacking up hugo!!

i want to walk "the stairway to heaven" i had an issue with what i thought was cal/mag def, but from every leaf guide with pics that i looked at, i could not find a pic or description that fit, so i doubled up the cal /mag and it seemed to work, but now the symptoms seem to have come back just as i am about to harvest, funny thing is that it dosen't appear to effect the leaf growth, i am beginning to think that with some strains, when the buds start sucking on the leaves, the damage manifests itself in different ways. some the damage stars on the lower leaves, turning yellow, starting from the edge and working to the middle of the leaf, others may start sucking from spots all over the leaf??
what do you think hugo?? btw it came back when i started the flush?? p.s. +rep for all you do here on afn, and your beautiful plants and documentation! shit that was a lot of typing!:buds:
