Hello Toofunky,
Looks like a deficiency to me of either calcium or Magnesium. This is prity normal this far through flowering but shows what your lacking. It's upto you whether you do anything about it at this late stage as the minerals you add may affect the flavour of the product. If your in soil I would just add some dolomite lime to the mix next time to stop it happening again.
You could add a good micro nute feed, or try some Epsom salts (magnesium sulphate), or a top feed of dolomite lime, but like I said, your nearly there, and if the buds are looking good you should get to the end without too much affect on overall yield.
Your plant is just redistributing its stored nutrients. Taking from the storage in large fan leaves and giving it all to your buds because the soil can't keep up, or is exhausted.

Thanks for the help, first time so wasn't quite sure what was going on. Buds are looking nice so I wasn't too worried but the pineapple still seems to have a few weeks left. And the liberty actually more like 4-5 weeks I would guess
 
Re: Yellowing Leaves HELP! PLEASE!

Your leaves both show different deficiencys. Your Pineapple Express shows a micro nutrient deficiency either from lack of nutrients or a nutrient lockout, second picture set of leaves from Liberty Haze show normal yellowing from either not enough light reaching them and/or low nitrogen in flowering. What is the medium that you are using? What are you adjusting your nutrients pH to? you want pH 5.8 for hydroponics and soiless (peat moss and coco coir) and pH 6.5 for soil. What nutrients are you using and how many millilitres per gallon?


here is a nutrient availability chart
