I find that my autoflowers are much pickier than my photo plants. They seem to use less nutes and respond faster to over-fertilization, they're less forgiving. Sucks about the N toxicity, I did the same thing on my first grow thinking I was being well-meaning. I have had decent success with topping autos, I let the plant grow 5 nodes [the cotyledons don't count] and then crop it down to the 2nd node. Sometimes I crop it to the 3rd node, but it's easier for me to LST 2 nodes in my space. Hopefully everything comes around for you, good luck!
