Premature hardening of new leaves

Several of the leaves pushed up by my cycad seedlings have hardened off before they are fully unfolded. My assumption was that this is caused by high summer temperatures (>110° F) but there doesn't seem to be consistency even within seedlings of the same species. Would temperature be the most likely cause or might it be something else? I would appreciate your advice.
