Hey Granny, thank you so much for the plant love.
The green colour is coming from the soil. I am not actually spraying the foliage. I spray the top layer of soil to keep it from going hydrophobic. I am using a reconditioned living organic soil. I followed Gee's advice in my last grow and alternated between kelp water and fish water. This early in the game I am not watering them as such, as the moisture in the prepared soil is sufficient to carry them for quite some time. This is when I spray the surface and I include microbe solution just to give the soil a microbe boost.
I hang out in the Gee Spot and that's where I do a lot of my learning about organics. You should check it out there
