So for trailer trash betty I am going to top her at 3 rd node I think it 4 then train through tomato cage and will be modifying cage so it becomes liek a scrog all around it ? Yup that’s it light training @Guy Cavallero@Jackalope
If you have not topped that plant don't. Super crop it by pinching the main stem below the top. Betty bushes great all on her own with a little help. Topping only takes the biggest bud. If you already have no big deal I guess. I have never topped then, no big deal. Betty also adapts really well.
