Sorry i am no help, but that's exactly how my hempies turned out in veg, and i tried literally anything. :s
So did you give up growing or what? This is my first grow and I've already got a page of mistakes I made for next time around. I think my problem is I nute burned these girls a bit then cut back on feedings too much and caused deficiencies. That and I'm going to do two plants I stead of 3 and scrog them. I hope I can get these girls to harvest but I have no idea if they're ok and I'm overreacting or if it's been too much damage and stunted or weakened them ruining the harvest potential. If I calculated time right they should be done around the second week of December ... What do you guys think ?
