Hi, Newb here. Seven Plants about 4 weeks in, I made the mistake of watering them everyday, transplanted them to 5gal about 4 days ago and stopped watering 3 days ago. At that time only one had a yellow set of Cotyledons and now almost all of their Cotyledons are curling up and turning yellow, some of the leaves are beginning to show signs as well. They were under fluorescent 80w, at transplant they were switched to 400w HPS which is on for the majority of the day then switched back to fluorescent to save electricity. The soil used is a mixture of outside dirt, Miracle grow moisture control, and miracle grow potting soil. Not sure of the NPK ratio, it should be around 15 15 15 give or take a bit. I suspect they are overwatered but not sure when to rule this out, I was going to wait a few more days for the soil to dry and then use peters 20-20-20 nutrient solution. Any tips or suggestions?
