here they are today. Still have some ugly leaves on the bottom of the older one. They are totally yellow and have grey spots now. yuck. trying to resist dumping a bunch of water on em. so, I'm callin em 3 weeks at this point, even tho the oldest is 3 and a half. So I'm about halfway to switching the lights over? I think I will be planting a real grow fairly soon. Getting a 600 watt HPS very soon, a day or 2..
