my first plant, was beautiful, now what happened??

So, I've been smoking for a couple years now and so I decided to grow some bud seeds i'd been saving.
For some reason, I germinated in January and started growing from there, so she's already quite large.
Anywho, lately she's been turning brown on the tip of the leaves and up top [this part worries me] where the smalll leaves surround the bud.
If anyone knows whats wrong with her or what i'm not doing right, please let me know!
i'm posting pictures, the first one is when she was healthy and green, the rest are how she is now.

can't see enough detail to diagnose the problem, i'm no expert anyway, StinkyAttic is the one who can help

anyway, heres a link that might help you out

It can be many things.

But if you started in January, that makes your plant about ready to harvested soon, yeah? (I should hope so, five months is a long time), it could just be the natural finishing process. The plant puts pretty much all of it's energy into finishing flowering, and will take away from leaves and whatnot.

But if it's NOT near finishing it's life circle (I don't know of any cannabis plants that take longer than 5 months, yeesh), then it could be any kind of disease/bug/nute burn problem or something.

I don't know all the facts, I'm still studying botany. Haven't graduated yet. :P

But that's all I can guess. Other people here should know something.

Yeah the pictures are kind of poor but it looks like its just getting close to harvest time.

the only problem with it being harvested is that the trichomes are still white, like, 80%


what now?

also, on the tips of some of the calyxes, they're turning brown!
i'm really worried.

The time its been growing shouldn't matter, only the light cycle will determine that. Have you been using nutrients? It appears it may be a deficiency of some sort, although it may be a complex one since it is effecting both old and new foliage. Test your pH also, to high or low could cause nutrient lockout. Some lockouts will then cause other lockouts. Over time this could cascade into a serious malnutrition.

Im not to sure, but it looks like you need a bigger pot maybe? and last year the calyxes on my plant turned brown and red, and like orange and shit, I wasn't worried about it though and that grow was fire. hope you figure it out though, beautiful plant my friend.
