i have 2 clones and a seed being grown in my closet. the leaves are starting to turn yellow on the outer edges and even brown in some spots. what is my problem? they were watered yesterday from left to right: romulan(clone), la confidential(seed), afghan kush(clone) information: AGE: seed-23 days clones-5 days POTS:11 inches in diameter, 9 inches deep, not sure how many gallons SOIL: Miracle Grow flower&vegetable garden soil (top) miracle grow moisture control (bottom) with rocks under for drainage. LIGHTS: 100 watt equivalent cfl hanging over each plant (2-4 inches) AIR CIRCULATION: small fan on rotate, not directly on the plants but air flow right above them. GROW SPACE: closet surrounded by white for reflection covered by blanket. TEMPERATURE: usually around 80 degrees C WATER: i get my water source from the tap but i leave the water out for a couple days to kill chlorine and make sure the water is room temperature. can anyone help me determine why my clones are showing yellow spots on the leaves? my seed is in perfect condition and it is under all the conditions above just like the clones.
