:wtf: Actually, if he's 7 weeks into flowering, yellowing fan leaves are completely normal. You don't feed with high Nitrogen fertilizers during flowering, which causes yellowing as the plant actually begins to consume itself to take care of its own needs.

And rootbound plants can still uptake nutrients, they just obviously will do it slower than non-rootbound plants. The biggest thing to worry about with rootbound plants is stunted growth, and it's not recommended to do a transplant during flowering...especially this far into it. Salt buildup and out-of-whack pH is usually the cause of nutrient lockout.

Just so ya know...
