We got an early start looking for leaf damage, and would turn over the leaves containing little holes and sometimes would find a baby that didn't even have a horn yet or a very little one with a horn. Is it true that once they eat the lead or main stem, the plant will not grow anymore? We have used BT this year where we saw baby hornworm poop and couldn't find anything. Do you think that will help? I hope it doesn't discourage bees and other good insects from doing their thing.

BT is highly specific to the target pest. The kind for killing caterpillars has no effect on other insects. It will kill any caterpillar though, not just hornworms.
