Well, if you know what you want them to look like, you wait until they look like that. Time will vary per plant and garden.
can't see how it progressed, but should have adjusted the things you were doing when all that damage started. could be a calcium deficiency and other things, not 100% certain. So you may need to reduce some things but it clearly wasn't getting enough Ca or something else was locking it out.
You should continue to give what a plant needs... if you want to save a little time or effort, giving water only at end with a strong enough canopy that won't limit photosynthesis too much is fine too.
