Hey all. My plants are about four week into vegging and the bottom two leaves are starting to yellow. Basically they are completely yellow and looking about ready to be completely dead. The ones above them are also turning light green with brown on one of the leaves around the edge. What is the problem? I havent added any nutes yet. Is it time to start adding some Fox Farms Big Grow right about now? I am using Pro-Mix soil with 40% Perlite. I dont know the pH and temp is around 78 degrees and 45% humidity.
