Shagrathanswered grow question 5 years ago Hi dude!
You should provide MUCH more info and good pictures to get a good answer.
It's almost impossible to say anything about your grow with that info..
What week of flower?
Dead leaves can be happening 'cos they don't get light and the plant won't need 'em anymore or there is some kind of toxicity/deficiency, could be something in the root zone etc. etc.
You should check the trichomes on the calyxes to know if you are near to harvest and if you should start to flush the plants if that was the question
