@@@Wilson_McNugget, I did the same exact thing to the cola on the gelato but on accident! Haha it was after I had already broken a main stem off and I thought for sure it was done, but it made a hard knot like you said and a really dank cola bud! I also have been wondering why i havenāt been getting much of a stretch from my autoflowers... I use lst method to create a bush like structure but Iāve never had any of my plants shoot up toward the light or get anything over 24 inches. Maybe genetics? Idk if itās my light I have the 1000 watt marshydro ts series. Iāve seen YouTube growers with same light but taller buds.. but yes I would definitely recommend gelato it gets my stupid high and smells and taste amazing
