Can you help me out with my baby train wreck?

[Rosebud]

Hi, this is trainwreck at 27 days in flowering. grown in FFOF, no ferts till three days ago and a very light dose at that. The fan leaves are affected and I think it is too early for that normal happening. All along from birth she had a darker vein in the leaf, i just thought it was her. I don't remember that last TW I grew. i don't have any heavy nitrogen to give, i just have a: 6-11-5, or buddah bloom which is 0.5-2-1.5.
I also have hPK, which is 0-5-4 which is from guana and something else.
This is my favorite smoke in the world, do i need to stress the importance of getting this fixed and now????:doh::doh::doh:

Thanks for the much anticipated help.

Here is one more picture.

it looks like it could use a little N to me. i've had plants fade like that pretty early in flowering. i will normally give them a dose of veg nutes after the 2 week stretch if it gets real bad. jmo looks good by the way

Yeah rose id just give it a feeding.

Use both the 6-11-5 and the 0-5-4

I dont know the mixing ratios but I'd make it quite a bit stronger than the mix your using now. maybe Double Strength....I'd feed her 2 maybe 3 times with the extra veg nutes...

My TW has to be fed N throughout the entire Flowering process or else I get a nasty def on the top of the plant.

Im no expert (obviously) but like Slowmo said it looks like a Nitrogen def.
it is only the lowest fan leaves that are being effected correct?
if so, Id say just up the veg nutes a little bit and watch it

She needs a little more N in her feed and she should be fine
