Are you or have you used chicken manure to fertilize or amend your soil at all? If so too much can raise your soil ph and cause a lockout of iron. Not sure if thats the case or not but looks a lot like iron deficiency. Not certain though. http://www.growweedeasy.com/iron-deficiency-cannabis
After reading that, I believe you may be right. No chicken shit added however I may have overlooked the importance of the fields ph. Any idea how to drop 3 acres down from 7.5?
