Hmm doesn’t make any sense. I thought your AvT and Stilton were looking good. I haven’t had one that short ever. Shortest so far was sour hound 16” and that still yielded over an ounce. I’ve heard avt can get big. Get u some auto gorilla BigSm0 runs them and gets like 8-10oz per plant. If u can’t get more then an ounce off that I hate to say it but u may want to quit lmao sorry but I had to. Just kidding though but you do have the lights what else could it be. That’s why I said start a journal it helps u keep track of what u do and what u do is written down and u can figure out what your doing right and wrong. Plus u can ask for help if needed. Run two in 7 gallon pots each. U should get close to a pound. Hope that helps. Seriously though I wanna see u succeed with autos.
