Here is the problem. If you take a look at the pictures below, you can see how the leaves on my plants are lightening up a bit. The PPM of my water is around 820. I am usng vitagrow nuttients. A problem that I am having is the garage I am growing in has gotten cold the past few days. The temps in the grow room I recorded last night were 54 degrees. the water in the tank is also very chilly as well and when I touch my weed plant it feels cold. I literally had to put my 600w HPS light between 6-9 inches away. Also, another thing. I was kind of being dumb and removing fan leaves that were in the way of nodes. Then I read up that you arent supposed to do that, and I cansee that the leaves ligthening up the most are the nodes without fan leaves. any suggestions?
