I had a few questions for you guys.
I was wondering why some of my leaves were curling in like in picture 1 I was thinking heat stress. Also in picture 7 the tips of the round leaves are yellow/brown? it's growing fine but i was wondering what caused that?

advice & comments are welcome

In picture 1 the edges are turning a little brown and
i was wondering what was causing that? none of
the other have been doing that. and on picture
two there are little brown spots on the big leaves
and the new leaves are all twisted? what's up with
that?

HEY snowman---could be your seedlings are a bit thirsty or your light could be a little close to the plant.The twisted leaves are an indicator of hot dry conditions.Looking good so far---keep up the good work!!
