yellow dry leaves

I'm growing a 1 month old blue mystic indoors in soil,temps 24C,150wcfl and from the first set of leaves that has now shrivalled and turned yellow it's been growing slowly but now the other leaves are showing the the same signs as the first leaves.I'm watering with ph 6.5 and fed once with miracle grow all purpose.Can anyone help?Here are some pics.

i'd find a better line of nutes. i''d transplant into something bigger too. next time you feed or water, allow for aa good amount of run-off...

whats your humidity? temp? dirt mixer? what is the ratio or pecentages it says on the miracle grow box for the nutrients? but from what it looks like it could be nitrogen deficiency or a cal/mag deficiency or it could be all 3. also how often is your watering? overwatering could also cause this.
