2 weeks into flowering and leaves are dying.

i don't know what is causing all the lower fan leaves to die all of a sudden. the temps between 50 -75. no signs of any bugs.
also, what should i do about the leaves?

if anyone has an idea:confused:

going to need more info.what kind of nutes are you using n-p-k,how big are your plants?are you growing in soil or hydro?

my plants at about 2 1/2 ft (tied down). i'm growing in soil.
for nutes i'm using "fox farm"-big bloom (0.01-0.3-0.7).

Do you know the strain of the plant, or whether its indica or sativa dominant? If its indica dominant, then Id say that shes using up the nutes in the leaves for that 'last big push'. All MJ plants do this in flowering. If its a sativa strain - which take longer to flower - then I would have to say that its some sort of nute deficiency. As most strains are a indica/sativa cross, its probably just doing its natural thing.

thanx alot, i really appreciate it!

Sativa's do this too.Alot more then indica from what I've found.
How big is your pot that they are in.
They could be getting rootbound.

Where are your photos? I can't tell.

Sometimes my leaves start to yellow 3 weeks into flowering, and I think this may be slightly sooner than normal. Jdog may be right about being rootbound.
Other than that, I don't know. Are you using to much ferts?

i transplanted a week b4 flowering into a 4 gallon pot, and used some vitamin B1. the strain is "NYC Diesel" (mostly sativa, i think). but the leaves are not yellowing, they're completely wilted.
it's happening only 2 the fan leaves. the new growths appear to be healthy and green, and it is budding.
i'll borrow a camera and post some pics in a couple hours when the lights turn back on.

ok, here are a few pics. camera is kinda crappy. i couldn't get a good close-up of the entire plant.
