I’m still just an amateur grower I live in eastern usa near Appalachia. This is my 3rd year growing my own cannabis and I’ve still got a lot to learn. Each year I go to homegrowncannabis.com and I purchase about $500 worth feminized seeds from them and I’m learning from my own experience through trial and error. All that been said I don’t feel like I’m any more experienced or that I know any more about cultivating cannabis than I did the very first time I grew it, I had a very successful harvest last year this year I’ve had many difficulties just getting a seedlings to survive long enough to enter the veg stage and even more difficulties simply germinating the damn seeds! This is by far my best and healthiest girl as of right now but my concern is this blackening around the area of new growth the strain is KILLER feminized and this blackening is only on this particular strain but it doesn’t look like it should be there at all… someone please help me figure this one out?
