I've looked everywhere and can't find anything similar to my problem. My girls are about 3 weeks old under 2 24w cfl bulbs at night and put outside in the sun during the day when the weather permits it. The first nodes are perfect but the second and third set of true leaves are curing at the tips so bad that they make a perfect circle. Nothing else is wrong with them besides this. The first true leaves are perfect and growing just fine but every new node just grows in this circle.
