Athosanswered grow question 6 years ago You are not feeding the plants and you wonder why they show massive signs of deficiencies? I understand wanting to go organic, but that doesn't mean starving it, buy or make your own worm castings or compost pile, it's very easy. I made a worm bin that I use for my garden.
Besides that, 2 inches is too close for CFL, they give way too much heat, try 4 inches.
Get a pH meter and EC/PPM meter and regulate your pH to an appropriate level (you can do it with apple vinegar for ph down).
