The plants are 2.5 weeks old. I germinated them in the medium and started nutes when i dropped the seeds in. The plant with the burned tip was drowing for a few days. His medium didnt have enough holes so i ripped it open and exposed the plants roots. Now it sat back up but the tip burned.
just use water until they are about 3 weeks old. with seedlings i use a mist bottle to keep the soil slightly moist - not wet. seedlings are easily over watered. GL
