First timer with autoflowers

Well, the ladies have a quiet week behind them again. In terms of nutrients, they got a little bit today, the rest of the week it was just water. The lady with the double trunk I tried to train with strings so she looks down. I spent the whole day working on it and the moment I put her back in the tent, I hear the knackle :( Left side is cracking, now she is exactly under the lamp and now she has her tied to the roof with a rope, so the fracture can heal again.
