Help with correct breeders terms

discarded reversed plant after pollen collection so no selfing and no temptation to smoke any of her/him I read selfing is harvesting seeds from plant self pollenated or pollenated clones from same mother but other 2 are very close in structure and yield but clearly different so thought it would be considered back crossing (BC) since all three seeds were same strain?

F1 is a cross between a pure male and a pure female. You would have what I would consider as S1 or "Selfed (Generation) 1". F2 is a cross between the offspring of F1 plants. "Reversed" means chemically treating a pure female to make it grow male flowers and does not have any influence on a plants auto flowering or photoperiod traits.

I do not understand what you mean by "reversing autos". In my mind that is not possible, that´s why they are called autos, they flower irrespective to photoperiods. Could you leave a comment or pm to explain maybe in further detail, please?

F1 is when you combine two different species to get a hybrid, f2 is when the plant self-pollinates, if you only reverse half of the plant and the other half, or if there is only one seed left, it would be F2, and if you got it, reverse the whole plant into a male, collected pollen, and then fertilized the other females, I believe they are F1, I'm about 85% sure.
