55cm plant in the 3rd week of flowering, is that good? What do you think? Since this is my first grow, I don't know if they are a good size to offer a good harvest or not, thanks!
It's a sativa so you can expect a lot more growth from her during flower... she might benefit from some LST to keep her under control and not too close to the lights... But the grow looks magnificent and I think you're going to be more than pleased with the harvest from them!
Good luck!
