Yes greenline. An extra 600w or 350 w LEd would be overkill.
As far as how many platn you can grow 4x4is really up to you. It's all about maximizing your space, but personally, I would go for 4 plants.
I just transplanted from a soil-less mix in solo cups into a top drip hydroton system. I moved from a GH 3 part 50% veg mix to a FULL strength veg mix. I also think I got some nutes on the leaves from the rings splashing and that caused a burn out, but I cut the tube housing to help the rings...

Is it shock...
Use an air pump and and air stone in a cup of water (like a pint glass or something big.) The bubbles will help humidify your area. Especially if your using a dome or the glass is under the light.
I have several plants that are two weeks old from seed and they are developing yellow spots on the leaves, not the edges.
Are they asking for nutes? is it a zinc deficiency?
Black spots, some where deep brown/ orange in color. It only formed on the top layer of material of the "Sure to GROW" cubes. I've read that using rockwoll it becomes more difficult to see these disease because of the color of the cubes.
Started with 13 'sure to grow' cubes in a humidity dome. All sprouted but mold grew on nearly all the cubes. Had a few more trail errors; thought I over watered, tried not using the lid, now its not enough water. Then they start curling up and falling over? All trial errors mold developed.
