Hey SmoothButter, great question, thing is it looks like potassium deficiency, but I rather think it's indicative of lockout because the plant is in veg and it's not really using that much potassium right now. So it's a lock out, reduce your PK intake, increase cal mag, and since i do see some signs of overwatering, make sure you follow a dryer wet dry cycle. Hope this helps ! 🚀
