Ya that could be the issue too being rootbound.. What size grow bag is that?
I will say that ive never had any luck at all with auto ive tried.. There are sum autos out there today that look to be not that bad, but over 25yrs ago when i tried em they all sucked... Hopefully its not genetics for u too..?
But there is this auto called the NYMPHO thats like the holy grail of ganja.... Nothing compares to it.. U havnt got high til uve smoked the NYMPHO... Hands down, high times award winning genetics.....
(Disregard that whole last paragraph.. Complete bullshit! Theres a cat on here that spews pages of that bullshit on here , just search for it on here if u want to laugh yourself to death..) Smh
