Demande de diagnostic

Nitrogen my friend looks to me did this problem start on the lower leaves and work its way up the plant ? if so its in need of more N. each strain is different as to its required needs some need more some need less are the leaves yellowing and then dying off and falling off the plant if so the plant is eating itself for nitrogen not got enough of it though I could agree with the other grower but my personal experience I would say it looks more like a defiancy more than an overfeed and i only base that on the edges of the leaves dont really look to me like they are brown enough overfeeding usually turns the edges of the leafs brown first and then it head inwards from there in serious cases it coulf be a lock out if you feeding scedule is heavy but my guess she needs more. Best of luck anyway brother :)
