I have 3 feminized seeds in my garden and all 3 have sprouted and are looking happy. It's about day 7 for my 2 medical mass plants and og kush seedlings. I'm not so sure what is stopping the growth on day 7 because I'm hoping someone would be able to give some of their knowledge as what is going on with them. I have them in 3 solo cups filled with perlite and coco coir each stacked with drainage holes and a stopper in the bottom to let the water hold if there is any runoff which then gets drained out. I'm not feeding nutrients yet but they don't seem to need it in fear I may burn them up too soon. They're under an led I got with my hydroponic table kit. (See images) I guess my only question is what is causing them to grow so slowly and what can I do about it? The first photo was taken at 5am pst yesterday and the photo without the magenta light was taken at 8:30 pm today. What do you got for me?
