A very sunny week that made the plants double in size and grow healthier. I didn't water once this week and the plants are good with it, thanks to @MadeInGermany. Pre-flowering stage has started this week and each day I can see more and more pistils.
As I expect the plants to stretch the following 2/3 weeks, I thought some little training would help. So I taped a couple leaves downwards in each plant-the ones that blocked sunlight from sidebranches, that will be bud sites in the future-.
