Your plants aren't growing because they are being burned alive. You should be feeding only water for about the first 2-3 weeks of growth from seed. And even then I would start lower than 500 PPM. Switch to clean water only and let them recover for a week or two. Also, lower your pH to around 5.5, and try to keep it under 5.9 and over 5.2.
dejayou30 Reviewed by dejayou30 on . Many weeks, sooo tiny I have 3 plants that I started about 4 weeks ago. They started in soil, under cfl's, in the attic, yada yada bad conditions to the hilt, but they are now in a perfect fog system. They grow very little each day, hardly any new roots and now that they have been in a most very ideal environment for over a week now, they are barely 1/4 inch taller. I must have stunted them severely or something, what with all my learning curve shanigans and such. Currently they are this environment: pure fog Rating: 5
