dudes its all good. let those leaves fall off. its all natural for the plants to go through this. you guys are over reacting to this because once the plants reach maturity and are ready for the buds to be clipped the fan leaves send all their energy and nutrients and thc goodness to your danky dank nugs man! thats why they turn yellow and then look like their dead and fall off. its because they are dead! CostaRicaSensi is totally right in what he said. dont add any nutes unless u want to taste them in your smoke and dont cut the leaves off...let them turn colors and once they look like they are dead then trim them...
