A couple plants not growing upwards is one of 2 things. If it's 1 out of 10 roughly doing that, it's the phenotype. Or it's the type light you're using. The pinkish purple lights have a bad tendency to do that. Add one or 2 600 watt(200 watt draw) roleadro 2nd generation led lights. This light mimics sunlight. All plants grow upward better when that's the natural response to growing under the real sun. Plants with sunlike lights added tend to grow 8-10" taller.
