you're doing good.. the trick with autos is to get them as big as possible before they show sex.. thats how you get decent auto yields.. alot of that comes from good genetics.. theres 3 companies i use for autos... auto seeds , mephisto genetics , and nirvana's auto line
strains i can vouch for
auto seeds - transiberian , mig-29 , purple cheese
nirvana - auto jock horror/ auto bubbleicious
mephisto - anything
I have consistently gotten the best yield/flavor/high from the comapny Auto Seeds .. They're by far my favorite company.
