She seems to be growing quick. I had some trouble with light burn, First time using the quantum board so I'm still learning the best distance and wattage. i upped the nutrients to about half strength Lucas Formula for coco. I also use silica as i have had good results with it in my scorching southern california heat.
I think it depends on the strain. I did a lot of LST on my last auto. I think it turned out alright, but I think that strain would've benefited from a lighter touch. I looked at a bunch of other diaries that let their auto of the same strain grow naturally and I think they had much better results. Of course, I only accounted for the plant itself. I didn't really look at lighting, hydro, etc..
