Help identifying plant issues.

Hey everyone just looking for some input on my plants. They are 3 weeks old under a Vela 320w led dimmed to around 50% and I'm using promix moisture control (best option available locally) and using Humboldt's secret nutrients . They are all growing well. The two in the back seem to have some issues, one is fairly droopy and the other has some discoloration in the leaves. Any input or suggestions are appreciated

I had some overwatering problems that made mine look like that. im fairly new to growing but i too am using golden tree for outdoor grow and started after i got watering under control and my girls are doing amazing!

They look over watered to me. Let them dry out between waterings
