Leaves

A few of my plants have leafs that are curling under at the edges. Not all the plants are doing this, which confuses me, they all have the same conditions available to them. I am using Fox Farms Ocean Forest, and also adjust the PH of my water so that it's neutral. I have a 4x4x7 grow tent, with a 400 watt light, carbon filter and inline fan, also a small fan to circulate air flow. I don't understand what it going on! I just planted them in 3 ga pots a week or so ago, I grew them from seed, they were a month old. Any ideas?

Sounds like over watering to me... Always start at the thing that is most obvious before working your way down to the nitty-gritty of nutes and such... (sorry if my advise sucks but I took some E about an hour ago and it is starting to grab me now. think its time to leave the advise to some other people for now...)

snap a picture if you can, it helps in figuring out whats wrong.

I've only water twice in the last week.

How's the humidity in the room? Do you have a fan on the plants? Just changing out the air in the room is not really sufficient; right at the surface of the leaves is where stale air needs to be replenished.
