12 weeks flowering any advice is welcome

Sup guys, how do these girls look the leaves are turning yellow and the top of the branches have good size nugs but the branch hasnt filled
any comments is welcome

maybe its the low quality of the pics but for 12 weeks flowering i can see any trics on the bud or leaves. what strian is that?.

when you say 12 weeks flowering, do you mean 12 weeks since you switched to 12/12 or since the first pistils showed up?

yea sorry bro bout the pics il get some new ones up soon when i flush them i think it could be a nute problem, i started adding abit more nutes in the last couple of weeks and thought it might pump the buds the buds up abit, im sure its an indica, had it in veg for 3 weeks and flowered for 12 (since 12/12)
