One more point as far as drooping I am reminded of when I was growing vegetables on my deck. They would start drooping at the end of the day, still be drooping in the morning and pick up by mid-morning. This was fairly frequent if I remember correctly. Also checkout the info at
http://www.kindsoil.com. The say that additional nutes can cause issues. From their site:
Adding ANYTHING other than water: This happens a lot, growers get impatient and that feel they can "BOOST" the grow or simply don't trust the system. Our system works exactly as we state Adding anything to your water or grow pots can slow and hinder your growth. It can cause low production rates, slow growth, PH swings or even just cause the plant to lock out and die from overfeeding. Our system is designed to be a water only system from veg to harvest, DO NOT ADD ANYTHING other than carbon filtered water to your grow. Patience is key, your plant will grow vigorously and produce proper flowers as long as you allow the soil to work for you.
Q: Can we use chemical regimens or extra bloom boosters when running Kind Soil?
A: No we do not recommend it, everything your plant will require, is fully amended in the soil. adding or using anything other than water can and will generally cause many growth/production issues. Your plants will produce large dense full size colas with nothing more than Kind Soil and water.
Others in the forum seem to be getting good yields with water only-super soil. I think it is just a matter of fine tuning our grows.
