8 days old, now yellow spots are forming. can you tell me what im doing wrong? i have 3 lights total. 2 CFL soft white 75 watts and 1 blue plant light 60 watts. I jus watered them and mixed the water with miracle gro plant food so hopefully that helps a bit. i also have a small fan on. I keep them under the light 24/7 so could that be a problem? New leaves are starting to grow but the yellow spots scare me. the temperature now stays between 78 and 83 degress F.
