bro your buds look amazing !! i wouldnt be too bothered about the leaves if i were you since the buds are so nice. but if looking at yellow leaves bothers you as much as it does me, here's my 2 cents...
i think that plants need nitrogen throughout they life, even during flowering, even if it is absorbed in decreasingly smaller amounts by the plant. so i would maybe try a very light all purpose fert, something like a universal 5-5-5 if you've got it available, mixed in with the tiger bloom. i would use a tiny amount, just so you know the plants have a little nitrogen if they need it.
best of luck with the rest of your grow, let us know how the smoke is
