I already have answered this question with „yes!“, but it became a desaster. So now I would say „no!“
But it‘s all up to you! What is your goal? Just have a little fun and if you fuck up it won‘t matter. Or do you need some medicine, and can‘t accept a loss. Is money important, or can you say „I don‘t give a fuck“, and start with more plants, just to choose the most healthiest ones before flipping them, and throw away the rest. How is your grow room? Are you height restricted, or won‘t it become a problem? And so on....
I couldn’t grow a plant without training, just because I have only 3ft (2,5ft before) height wise. I hope you get what I want to say... and I can just repeat what the other dudes said, just keep it simple, it will give you most benefits. There are still so many aspects to learn and adjust, it won‘t get boring anyways! Actually the most important question is, WHY DO YOU WANT TO TRAIN YOUR PLANT? Only fun? Than do it! Did you read, that your yields will be way bigger with training? Than don‘t do it!
