Having some issues with my new seedling with this yellow spotting using FF Ocean, Frog and additional perlite. Adjusting water using GH Ph Up and Down to between 6.2 to 6.8, TSL 2000 light hung at 28in at 50% power right now as well.
Using Neem oil mixture as well to try and combat any fungus or bugs, cant seem to really diagnose the problem.
