Idk. I don't agree with much of this at all. A 1st time grower can easily get a great harvest not needing "luck", but just by not being dumb. Plants don't need much. Soil/meduim to grow in, food wether organic or bottles, lighting, decent temperature and airflow. Thats it. Plants outside don't get lux meters and ppms tested and blah, blah, blah. People(especially new growers) try to do too much. It's the Tony Montana Scarface syndrome. Want to be "the man" and not care to learn or have good genetics and equipment to do it the right way. Topping? Maybe not on the 1st grow cause you have no idea how it grows. LST? Absolutely go for it. Can't hurt anything by just softly tieing arms down for more light and canopy management. Autos are not really as hard as people make it as long as you don't force more on them than they need. They can be traines, topped, transplanted and everything a photo can do except from producing anything smokable from a "clone". Biggest issuse is they usually like lighter nutrients. As long as OP doesn't over water and over feed, 15 grams from 3 plants was you as a grower and not you as a 1st time grower.
