Old Thread, I know. But, My two cents. NEVER top autoflowers, they don't have time to recover like photoperiod plants. They have 2-3 weeks usually before they start pushing out pistils. That's why it stunted so badly. Also, Autoflowers are almost always no where near as hungry as photoperiod plants. The rule of thumb with autoflowers and any breed you're not familiar with, for that matter, start with 1/2 strength nutes in cool soil, it can grow into hotter soil but it can be stunted from nutrient burn as well, so always go easy when you don't know how it feeds. Happy New year
