First grow ever: micro Hindu Kush Auto

This plant is doing so well! The leaves are growing fast and it seems really healthy. Since she was growing so fast, I decided to start the feeding with nutes. I started with a light feed to avoid strong nutrient burn, but the plant took it well. I've had no burn and no deficiency so far. I put too much water in one shot though, and even if the plant didn't show any sign of overwatering, the soil took too much time to dry, resulting in some algae forming on the surface and on the perlite after three days. In order to avoid any pest of disease, I scrapped the first 2-3mm of humid soil with algae, and replaced it with fresh soil. I then waited for the soil to be totally dry before watering again. The plant showed no sign of stress during this time. The next day, the soil being dry and the plant healthy with three set of full leaves (she was about 15-16cm high at this point), I started low-stress training, and watered it again, with nutes. I was not expecting to start this early, but it seemed she could take it. And it worked very well. She is adapting well to the LST and, after two days, she is still growing fast and turning to the light again (photos next week). The plant is producing a light smell, kind of chlorophylly-pepperminty (pretty nice), only noticeable from up close, when inspecting or watering.
