HELP! Leaf Yellowing.

Okay, so I got the Bubblicious on Saturday, in a small growing cup, and the Trainwreck and Pineapple Express on Sunday in a growing cup as well. ON the same day for I received them, I transferred them both to one gallon pots. There was slight yellowing in the Bubblicious when I bought it, and the tiniest of touches on the other two, of yellow. I just took these 10 minutes ago, and the yellowing is spreading. The soil is SuperSoil from Home Depot, and I have not given them any nutes yet. I watered during transfer, and that's it.

They are in a cupboard that is 2.5x2.5x1 feet, with 4 100watt (equivalent, 23 watt actual) 1600 lumen CFLs . The box is stable at 82 degrees.

What could this yellowing be caused by? Was it an issue from the grower? Is it an issue with me, because it's spread since I brought them home? Should *I* nute them now? I was trying to wait until they established themselves a couple days in the new environment before doing so. I wanna nip it in the bud. Any help would be greatly appreciated.

no one at all?

That soil looks like it retains too much moisture, almost muddy. Transplant and add some perlite to the mix, 20% should be fine. Perlite will help drainage and allow air to vent through the soil.

Yeh I agree with mj on adding the perlite at least. Need to get some oxygen in between a lil of the soil so it can breath well. Keep it simple with plain water till it's healthy.

P.s. When in doubt, flush it out.
