Hey DGC, just had a quick tip to share to anyone that encountered a non flowering auto. by stressing out the autoflower that will not switch to flower to force flower. The auto i had did not flower for 3 weeks after the others had already flowered. Turns out a simple method to have it flower without having to change the light cycle is to stress the plant out by trimming off a good majority of the leaves and maybe even super crop a branch or 2, as i did and it will flower within no time. It actually ended up being the biggest yielding auto i have had. Just wanted to share the tip for any auto growers out there.
