go BIG or go home LSD-25

Second week and the first problems arises. This is the first time for me indoor so I'm not very familiar with the lights, and the plants stretched too much because I couldn't find the perfect height but now I think I'm good. Also 6 of my 9 babies have curly and twirly leaves. It happened with one of my plants in the previous grow and it wasn't a big of a deal, but now I'm a bit worried. It could be genetics but it also could be my fault. After some research I think I found the problem : the wind of my ventilator was too strong so I turn it off. Now the situation seems to be better, we'll see next week if I was right. This week I also started to give nutes, but because they are a bit curly how I said before, I don't know if they like or not. I adjusted the light to 60 cm ad dimmed so it gives 17000 lux, I know that I need to measure the PAR for the best results, but you know, a parameter cost too much, and this is the best I could do. Some of the plants are already starting to show some shadows of purple, and I'm really excited to see how they will be next week, cause I want to train them as soon as they get a Lil bigger.
