In need of advice

I am having some concerns about my little girls.... They mainly look healthy, although about four nodes up and down from there the fan leafs and some of the budsite leafs are turning yellow. What should I do about that? Also the fan leafs tips are curling down is this some thing i should be woried about?

how far into flowering are you? What nutes are you giving them and how much? I would say it looks like nitrogen deficiency

they are 2 weeks into flowering..I am useing fox farm " Big Bloom" ..

big bloom isnt really flower food. its more of a supplement for plants. npk is less than 1-1-1 for big bloom. you should use tiger bloom in conjunction with big bloom.

yep nitregen def..

wouldnt worry to much mate most varieties do this in flowering , but if you give her some n she will stay greener a bit longer, check out some other flowering pics , plants tend not to use so much n during flowering, but a little does help i find..
