Q.Frost Got New Horse Chestnut Tree Leaves
I had germinated horse chestnut seeds in my crisper from late fall untill they sorouted in very early spring end of winter. After they grew about a foot with 2 big leaves on each i transferred them out to my green house(may month). That night we had heavy frost. The middle buds are growing. But the 1st new leaves are brown and dried up. The middle buds didnt seem to do any growing untill after the frost killed the 1st leaves. Will they be ok?

Likely, they will be fine! They may change shape a little as they adjust to the new growth, but they shouldn't suffer too badly.
