Urgent Help needed please

my plants are dying the larger leaves are shrivelling up. The smaller leaves are fine though but think they are working its way up the plant. HELP Any Ideas? At first I thought it was where i wet the leaves whilst watering. I heard that some people leaves fall of naturally but I'm unsure. I don't think it could be root rot as the roots have only just started to show at the bottom.

P.S
My plants, how long do you think I have to go til havest,

On my other plant one of the leaves is turning red

the leaves will go yellow in flowering and how long have they been flowering for

Cheers for the reassurence, you can tell its my first grow.

looks like nitrogen deficiency, try feeding it some light veg nutes....just an idea

I'll try a switch to them as at the mo i'm using multi purpose MG

ive had same problem my whole plant is yellow now only 6 days left expect all them to go yellow towards the end the leafs are using up nitrogen as when they go onto flower the plant doents really use nitrogen uses other chemicals phosphorus i think its sweet though ive only learnt off this riu its good knowelege

yeah RIU is the best source i found on the net only one that made me want to sign up cause i couldnt see the pictures that go with all the good info lol now i'm hooked

check my leafs on post on plant problems called 7 weeks flower signs of male flower maybee

yea id say nitro. but the topps look good
