Let me first start off by saying that I'm new to this site, so I'm not really sure where to post this thread, so I apologize if I'm in the wrong section, this is my first real grow and I've noticed strange yellow splotches on 3 of my plants and I'm hoping someone can shed some light on this problem. They where started from seeds (GHS white widow) I have them under a 1000w hortilux super blue dual arc bulb, the hood is air cooled with with a 6" 470 cfm inline exhaust fan, temperature is 78 degrees lights on, and 67 degrees lights off, they are on a 20/4 light cycle, the grow medium is my own organic soil mix of perilite, vermiculite, bloodmeal, bonemeal, water has been tested at a ph of 6.5, and is room temperature. Please help I don't want to lose these little babies, and I feel like I have all my basis covered.
