@NiceCrits, great to hear from you! I think it was a combo of nutrient burn and light burn. Didn't check the pH of my runoff-water just yet, but I will definitely do that!
I probably need to lower the pH of my input water (the soil was quite acidic when I checked in Week 2) and chill out with the nutrients for another 1-2 watering's.
I'm pretty new to growing, so I'm learning on the go. And yes, I'm not planning on overreacting. If I'm remembering correctly from my biology degree, almost everything is fixable on a plant!
So thank you for all the helpful information!
