yellow leaves

Im growing Northern soul skunk No1 and have had a few problems that have eased but would like to know why my leaves are yellowing.
I first had my plant in the cupboard but it grew so bloody big i had to put it in the shed, lucky for me my mrs doesnt work so shes able to take it out of the shed at 8.30am and put it back in at 8.30pm, i only have 2 weeks left of flower (and boy is it flowering) but the leaves are turning yellow, some threads say its due to ph and some say its because its coming to the end, can anyone advise me on this problem??

the plant is also 8ft tall and im using dwc

i have some pics in my album but unsure how to put pics on thread so feel free to hve a look.

it is natural for the fan leafs to turn yellow when nearing the end of flowering. sounds like you have done everything right, at 8' and 2 weeks to go. have a great harvest.

phew, i was thinking i had done something wrong, shes budding well so hope to have a good harvest. was told by a few to get rid of it as i put it into flower at 14in but i thought what the hell, ive come tis far i may as well grow it out, glad i did
