First Autoflower seed

This was my very first grow ever and so It is a good job but I do some mistakes: 1- Pot size, a pot that I used is not enough bigger 2- I placed cage too early and plant was attacked from slug and rat 3- At the start of flower I didn't give it water and It dried but after that It recovered very well 4- I harvested my plant one or two week later I collect 7.64 gr after dry phase (buds + stems); so I collect 5.17 gr of buds.
