You should not top auto flowers.. Everyone says this.. And this is why.. Your plant from observation is still Flowering and starting to Stretch so all you did was stunt her growth.. Or stop her from flowering but form the looks of things.. She's gonna flower.. Others nutrient advice is pretty good they have said enough about that.. except maybe the whole you should have started 1-2 weeks ago... Part of the reason your plants look good is because you haven't started early like a lot of folks do. but the topping. man that makes me sad :(.
