It is a bit overwhelming but I think it will all come in time . This is my first actual grow and really didn’t care for them until I seen them striving so well . Next time will be different .
No haven’t done any testing or feeding expect for when I started noticing the yellowing . I figured like you said being there were hogs and chickens before that that it would be very fertil ground .
Leaves turning yellow all around the bud sites looks like it’s only happening on one branch though . The last photo is the branch right next to the yellowing one . bongsmilie
