First grow Girl scout cookies

This is my first grow. I have growbox with 250w lamp with blue spectrum. The first few days watered with clean water with stable ph. But due to the fact that I did not raise the lamp when the first large leaves began to appear, some defects on the leaves appeared due to burns from the lamp. But later on I raised the lamp and the leaves began to appear healthy, saturated and bright green. I use fertilizers from GHE. In my opinion, plants grow quickly and well.
