yellow leaves

i have a mother that i am flowering out and she is doing some weird things her leaves keep turning solid yellow and falling off im in the 5th week of flowering...I think that its because its root bound needing to be transplanted im using all foxfarm products and have NEVER had this happen..however i always can learn so please help im stumped and guessing i realy would hate to lose her shes a strain called SUPERGIRL

Leaves turn yellow and stems of leaves turn purple? I had that happen way back when I used GH and went with super bloom fertilizer. Super low in nitrogen. Plants still need nitrogen in flowering and don't need as much phosphorus as most companies will have you believe.

Rootbound plants don't have their leaves fall off. They droop and growth slows drastically.
