Whats wrong with my plant? (Leaves curling, dying)

My leaves are curling up and dying for the last week. I'm about 8-9 weeks into flowering and my trichomes are still clear. About a week ago the edges of my plants started to die. Could this be because I don't have enough light?

any help would be great

wut r ur tepms also how much are u feeding

The same thing is happening to me. I searched around here, and found various theories from people. Some seem to think lack of nutrients, others wrong pH, still others think having the light too close. I'm a newbie myself so I'm afraid I don't have much input. I figured I'd give a bump though and see if anyone knows for sure what the answer is.

Anyone?

the pics are a bit hazy m8! she looks way off ready, do u have a decent light in the right spectrum? the leaves will naturally die off towards the end as its the end of the life cycle, dont worry if thats the case, have u started flushing yet,, wat strain is she, give us some more details and it may be easier to tell

The visible dead patches on the sun leaves could be caused by a pest or pathogen. If you've got a magnifying glass examine the bottom on the leaves for spider mites. If you spray some water on the leaves you can sometimes see the little webs too! Fungi tend to infect the stoma in the leaves, if you can get hold of a low power microscope you could check that out too. If it's an infection then humidity is your problem!

if you are that far in flowering, flush them with water they will be fine.

Yeah this appears to be something to do with nutrients. http://ag.arizona.edu/pubs/garden/az1106.pdf Look over that.
