the markings low down on leaf tips,id put that down to them resting on the soil,its natural for the low down stuff to get a bit manky as the grow goes on
one of them went a bit weird early on but straightened itself out
a rarety but it happens
first grow looking great
always issues and problems,ya ride them get over them and get some buds :smoking: every grow gets easier/bigger and better
we may think we dont learn much,but the experience of a grow under our belts
keep at it.
good luck n keep er lit
