Your girls could should go another few weeks simply so they can eat and produce more because they have that potantial,you just have to tap into it. It looks like they are hungry, very hungry. Some flowering plants require more feedings per week than others because they eat more aggressively. The way that your plants are yellowing shows that they are suffering from a nitro defiency so feed them a few more times and continue the flowering cycle so you gett more produce. As an example I am growing 2 k2's under identical conditions one was totally satisfied with 1 feeding per week and the other was a greedy bitch, she is never totally satisfied but grows like hell and is putting out excellent buds. You girls are talking to you the best way they know how so listen and watch them. Good luck

your plant is taking the nutrients it needs from your leaves, it's not a huge problem. Especially this late in flowering. The fan leaves dying won't harm bud production this late.

Thanks guys for replies, I did start to give them more food but then the leaves started to go purple, so I flushed them, Was I right? As I understand the leaves go a bit purple due to cold?

Is it ok to prune off the large yellow fan leaves?

yelowing in this period is normal.nice buds btw
