Welcome to the disappointing reality that growing autos can bring.
You have seemed to do everything right.
Yes your plant will survive. No, you won't get much yield. Yes, this is normal for autos.
Unless you have mega lights and premium nutrition levels and growing techniques, autos generally are a big let down.
Any defoliation administered will stunt young plants, due to the reduction of energy production.
Apart from flower growth, there will be very little plant growth, and you may be lucky to end up with 10-15 grams (dried weight) all up, as a guess.
Hope this helps,...........
