Don't over water it...Ph your water you use and at this cycle it's safe to use distilled water but you need t Ph it first. You can use RO water but you will still need to Ph that water as well. Make sure it gets plenty of good quality light and you may need to have a gentle fan moving the air around as well. That will help thicken the main stock and allow for more nutrients to be taken up later on in it's life cycle.

Happy growing!
