Got three little 7 day old sprouts under 3 42W CFLs in miracle grow potting mix. Two of the three have weird brown spots on them, the one closest to the intake fan and the one in the far corner middle one seems unaffected so far. The temp at soil level was reaching 90-95 I have since remedied that problem with the fan attatched to the lights. The spots just poped up today when I check em. To be totally honest I haven't been using a ph meter for my watering. I plan to fix that over the next few days since I got paid. So did I burn the plants or the ph hurtin em or what?
