Well, I guess you need to inform my plants of that, they don't seem to realize they can't uptake those micronutrients at the 5.5-5.8 PH they are sitting in.

If you watch the Harley Smith videos, he talks in some of them about how red light promotes root growth. So I switched to 2700k for cloning and have had great success. I then switch to 4000k for veg and then to 3000k for flower (I have separate areas for each) No need to spend much on the cloning area either, just pick up a few 2700k led bulbs and pop the diffusers off. I only do a few. clones at a time and use 2x 15w bulbs for that, so no need to build a fixture for that.

it's kinda gross and a great way to promote mold growth, under that carpet is a gross pad that absorbs liquid and grows mold.
