With enough perlite in the mix (mine are usually closer to 50% by volume), it's very difficult if not impossible to "overwater" — which itself is a terrible misnomer because the issue isn't exactly too much water, but rather not enough oxygen in the root zone. As long as your pots aren't sitting in run-off, this shouldn't be an issue ever, specially with fabric pots which allows more air to diffuse into the pot.
I'm only saying this so people with wilting plants don't try to overcorrect the issue and end up underwatering them, which results in pretty much the same symptoms.
