Sick seedlings

i dont agree to my growmies , you have been writing your light is an 50cm and on 60 Percent, thats pretty perfect. I never dimm the small lights i just rise the lights. I start my seedlings with the sf-1000 on 70 percentt so iam pretty happy with your lightmamagement. feedings lookk good to me too and the seedlings are just alittle yellwoish..... no big thing. just some calcium and magnesium should help them, dont forget to calculate it into your ec....... i think you might have had some ph swings here so the plant could not uptake the food or you waterigns were poor just check back your feedings// waterings

You need to raise your light. LED I start at 20 inches and back off or move closer depending on what my plants want.

Hey, that sf1000 should be a good 24 inch away during seedling, this could be the reason why your experiencing the issues you are, you also may want to look at raising your temps a bit, my night temp is 18 - 19c with day around 25ish, hope this helps happy growing 👍
