What a sweet little plant! Your leaves are a nice color, but the curling/drooping is definitely of concern. I would move the LED higher if possible (although I know that's tricky in a micro grow!) as blurple LEDs can definitely damage plants if left too close. 10-18 inches is generally a good range with LEDs. Make sure your watering is on point as well, as I could also see overwatering causing the issues you are experiencing. I like lifting the plant's pot and judging the weight (water when the pot is nice and light) or by sticking my finger in the soil (dry down at least and inch or so). For nutrients, I would try Megacrop as a very easy, economical, all in one. It very very cheap and is powdered (easy to ship if you want to buy online) but still great quality. https://greenleafnutrients.com/product/mega-crop/?v=3e8d115eb4b3 There are some great grows out there from people only using Megacrop. I wish I had known about it for my first grows. Hope that helps!
