Critical Orange Punch-My First Grow

I added 2 ml per 5 liters of bio bloom and top max, of bio grow oh added 5 ml on 5 liters These days I'm using rainwater and to lower the pH I use wine vinegar. Every day I lowered the plants more and more until I obtained a complete exposure of the whole plant to the light. Now the night temperature easily reaches 19/22°. unfortunately today the fan broke that I throw in the air, in the next days I will go and buy a new one.
