YOur plants look great iarbaman :thumbsup: . At this point in the grow, the bottom leaves do turn yellow and die off. So you have nothing to worry about there. But also at this point in the grow, you should be using any nute. Using the nute/fert at this point will give your bud a harsh taste and won't burn as good after harvest. Other then that, your plants are beautiful. Good luck for the rest of the grow and the well awaited harvest :thumbsup: ...
