has anyone had this problem? first noticed little brown spots they get bigger the next day and by day 3 the leaves have turned completely black. 5 out of 16 plants are doing this. ive tried flushing, i tried epson salts, p-h is around 6.9 in soil...plants are 6 weeks old, problem for past 10 days. ive searched thread after thread, looked at hundreds of pictures and none look like my problem. again...leaves have tons of lil brown dots that gets bigger by the day and by day 3 that leaf is dead and black. any of you exp. growers ever have this problem? anybody at all? im not a noob but im sure as hell stumped.......thanks for helping. also...i do organics on the feeding and not very much either.

Sounds like mold or a fungus is attacking your leaves from excess humidity..overwatering, or low temps, or a combination of both.

^That's what I was thinking, too. Crank up the fans, or add another oscillating fan, spray them with some neem oil, and cut off the effected leaves(as long as there's not a shitload.lol). Is it mainly the lower leaves? If so, cutting them won't be much of a problem. If it's the upper leaves, beware, and it might be better to let them die off on their own. Tough call, without any pics.

Also, since they're still in veg, you could use some chemical fungus control stuff, and not worry about it effecting the quality of smoke, like it would if you were in bloom.
