2 summers ago I did a test with autos , in my g/h in 3 gallon pots in coco G/H Nova nutes ,terpinator ,Rock resinator
Trans Siberian 1/2 of 12 got slapped bent twisted & squeezed 3 weeks in before any flowers (fems)
the abused girls skyrocketed growth to get to 7 ' , the virgins all six stayed small & quickly flowered
the abused took 6 extra weeks to finish but the yield was massive due to huge plants that got tippy real quick
But auto don't work on my migraines not one yet , they worked on joint pain but no didn't faz me no high
U can top them but do it on the 3rd set of leaf no later imo
