they look good other than the yellow

You can add as much N as you want it wont do shit. The damage is already done, salt build up. Use better soil next grow and make sure the plants are green and healthy before flowering.

it was cause lack of food.. I appericate all the info guys!
im doing aero right next to the soil to compare the results. so far aero is far superior. not a single problem.
what kind of soil would u recommend buds?
