Fucking Hermies man! I agree with your trusted advisor - keep everything as consistent as possible. Find that sweet spot and keep it. Sometimes plants just suck...bad genes. The white opium I've been having trouble with has been a bitch since day one. Nothing different and yet she is fried with nute burn. Your plants look great though!.. and you taking immediate action was a good move. Im praying your hermie situation ends. Best of luck.
