my plants all look great again! although i flushed, i only flushed each 2gal pot with 2gal of water not the 5x suggested, this because my run off wasnt that far out of whack at 5.8. And i flushed with ph7 water not my ph8 tap water. i think i had Mn toxicity caused by possibly not ph'ing my water after i added highly acidic seaweed extract w/o ph up. and then gassing them with the epsom salts. yes, i too used 2tsp/gal NOT one. But is was, however, Manganese, not magnesium, that did me in. I had quit using GH hydro nutes Micro (which has Mn in it) for this grow. ooops. But honestly I DONT KNOW STILL IF IT WAS DEFICIENCY OF MN OR TOXICITY!!! I JUST FEEL LIKE IT WAS MN because i was giving them Mg. The description in the chart below also doesn't quite jibe right either because it says younger leaves are affected first, and mine were all older, lower, larger, largest leaves. But what ever it was, flushing it out was the right thing to do, along with stabilizing the soil with the lime water.
so after "flushing" (i add quotes cause it wasn't done right), i watered with about one liter of water with the dolomite lime in it that soaked overnight (also at ph7). the leaves after two days looked like they were actually healing. not that the necrosis got any better, but it seemed blacker and kind of like 'sealed out' of the rest of the leaf. and the other leaves didn't start any grief. so anyway. i got this chart from a pm from Kodiak:
i hope it shows up so you can see what turned me onto the concept of MN toxicity, and saved me, along with Mitakoye, from killing them with more epsom salt. now am harvesting the most killerest buds i have grown in three or four years, no shit. i have some pics here in a few....
here's one after the flush/lime. this pic shows what i mean about it looking like it's healed itself up. i really impressed myself. too bad i dont know exactly what caused it but i guess all's well that ends well:
