^^ what he said, they grew too tall and spindly. Start over and use Daylight spectrum bulbs 5500-6500k, 100WE-27w. I would use either 4 or 6 bulbs with 3 plants.

Also make some kind of enclosure with a reflective interior. That looks like an Attic or crawlspace, so making a Vented box should not be very difficult, spend a few more dollars and get a Light Timer, materials, Nutes, Temp. Gauge(Thermometer).
Doing it right the first time will provide for better results, thus making you much more happier with your 1st grow.

Good Luck.
