hi stco,
i dont have a huge amount of plant diagnosis experience, but ill tell you what I think it could be......
looks like it could be a micro deficiency. ( zinc? calcium?)
or a nutrient burn issue.(although-fuzzybuds-I start giving my plants nutrients in low amounts as soon as they sprout)
first pick looks a bit like overwatering?
maybe check into the possibility of a bug infestation, although I really dont have much experience with those types of issues..maybe somone who does could clarify.......
hope this helps and happy trails
