Thanks for the information. Tell me if I understand correctly that if
we optimize conditions for growth, the plants will more quickly form
growing tips that are free of the pesticide's effects (and we can then
remove the damaged tips). Is that it?

Luckily we have a drip irrigation system that will enable us to keep the
majority of the plants watered well. Also, we're well-stocked with
high-quality organic fertilizer (Symphony, derived from organic poultry
manure).

Hope it all bounces back.
