Outdoor plant, leaves turning purple / black

[smokealot123]

you need to give that some ultra bloom.. about 1 cup full, then leave it in the sun without water for 2 days, then when it shows sighns of weakness clip the top cola and your perfect, all set.:thumbsup:

nutes on harvest week??? are you nuts!?

when you say black, it it black or deep,deep,deep purple?

either way, if its growing, black buds will be amazing!

its the temps tho, since purple usually is made at 16C nights or so, and your even less

are you having hot days?
could be the massive switch in temp, not necessarily the cold? just a thought...

Im having the same problem, like he said I think it might be from a big change in temp. Over here it will be hot and humid one day and then the next it will be 50 degrees F. On a couple plants the dark purple/black leaves went back to normal in a couple days. Im still not exactly sure what it is or if its bad but once i find out more ill post it

I had similar issue last year, in my case it was weather related..

as long as the black/purple doesn't rub off like a mold or something you should be ok...
