Royal Gorlilla Auto

Just started 2nd week. I'm not shure everything going well because this is my first time when I'm growing. But so far I can't complain. On Monday morning I found all my plants have bright leafs. I thought is because I put lamp lower from 75 cm to 60cm. I'm not shure that was first symptom of burn delicate burn but I put back my lamp on 72cm. After one day they are darker and I think everything back to normal. They going up. :l
