So my plant is growing in 1/2 miracle grow 1/2 coast of maine potting soils. I put 1/8tsp of miracle grow blooming nutrients after i noticed purple spots on the bottom of my first set of leaves (which you can see at the link just below this line). See: http://min.us/mUQAB9G66qH8z Now, on one of the two leaves that originally had purple problems, i'm seeing evidence of a deficiency. See: http://min.us/mQk7cJck1mqvW What deficiency do you think it is? It's more a yellowish tint. Sorry if my photos aren't well-colored. I'm growing under two 30 watt 2700k CFLs and one 45 watt 5500k CFL. The 5500k is closer to this plant. I'm also growing in a PC, of which the average temperature is something like 75 (near the plant, at least). Thanks!
