So I've got this lowryder #2 on a 20/4 light basis in a PC grow box and its now about 3 weeks old. 2 days ago I moved it to my shed and everything was good for the first day but today it had a few marks on the leaves. In the shed the temperature is quite lower during the light time its around 20 Degrees Celcius and during night its around 12 Degrees. Before moving the box in the shed it was 28C during light and 17 during night. Humidity is quite higher in the shed, staying around 40% during light and around 55% during night. I use soil and I still havent introduced any nutrients because the brand of the soil says that it has nutes for it for about 4 weeks. Maybe these where cause due to the change of enviroment? Or maybe its time to start introducing some nutrients? What do you think?
