Very nice though just tune in your grow and maybe higher ceiling. They look like sativa, maybe indica next time ,it won't get too tall. It's all about learning and tuning in.
Enjoy the bud and next time start a mother and have all females.
It seems as if the stem is trying to grow roots from the bottom (the fuzzy white stuff). It seems as if the water temps are cooler than they should be. I don't have a thermometer at the moment, but judging from touch I would say that the bottom container holding the water is about 70 degrees. I'm just about 100% sure that the reason for the top cola being burnt, is because of the lights. When I couldn't move the lights up any further, I had to sit there and watch. I'm using the pre-built rack in the closet to hang my light from. Its frustrating because I NEVER use the dosage that FoxFarm recommends from the feeding schedule. If anything, I only use a half of that amount the schedule says. I always check the pH, too.

I figured that it was mostly sativa with a few bit of indica, but I couldn't tell before I grew, because it came from an unknown batch. This is just my practice run, before I go into cloning a mother Blue Moon Rocks. Still haven't decided on what system I'm going to use next for cloning. Thanks for the help!

a note. A plant always grow 2-3 times it's size after flowering.
What is the exact term for flushing?? Is it pouring pH adjusted water onto the surface, and then draining the WaterFarm, repeatedly, and then do the same procedure? I guess what I am trying to say is, how do you know it is flushed, before I apply a fresh batch of nutes. I don't want to THINK I flushed the roots, and then make the mistake of adding more nutes, causing nutrient-burn.
