I went to the dispensary and picked up 4 clones. I saw that they had roots coming out of the starter cubes so i transplanted them to soil. I have them growing on a 18-6 light schedule, with 2 grow lights about 4 inches from the top leaves. I've noticed that the bottom leaves are dark and have what looks almost wrinkly. Anyone have some good advice or suggestions? I would really appreciate it thanks guys.

What kind of lights are you using? What strain? What kind of soil? Are you fertilizing them? Ph of water? You really need to give us more information bud.

I'm using a system by hydrofarm for lights. The lights are agrosun full spectrum light tubes. The strain is a kush of some kind I can't remember what they said it was. I'm using miracle grow soil with fertilizer in it.

That could very well be your problem. From the symptoms you described, it could also be a phosphorus deficiency, but I kinda doubt that it. And if you are talking about the agrosun fluorescent tubes, good luck bringing that plant into flower with just two. Those two lights might not even be enough to keep that plant alive, which could also be the reason for your problem.

edit: I say you wait it out a few more days, a few wrinkly leaves is no biggie. Even a few dying leaves is no problem, just clip those off.

edit #2: could be low humidity too. 40-60% is good

thanks man, also the room temperature is 60-65 degrees F. I dont know if that could be it or not.

That could be part of the problem. I keep my cab between 80-85 degrees F. Also, check the luminous output of those lights, and your grow area. I personally use a little over 7,500 lumens per square foot in my cab. But I have heard you can go with as little as 2,000 per square foot.

It says 2735 per tube. I'm thinking of getting some more lights and hanging them on the sides of my grow area to get more light.

i also got some plant food for the plants, because I read that the tips curling up and turning brown could be a phosphorus deficiency.

If it's only the lower leaves, it sounds like they might not be getting enough light-- with the grow lights so close to the upper leaves, it might not be filtering down.

Extra glow lights sound like a good idea.

Also, if you increase the heat and light in the growing area, you'll need to increase water as well.
