Good catch backing off the watering that’s the right move and your plant is responding well already. The canoeing (leaf curvature) and rusty edges typically signal water stress or pH swing, and reverting to your previous schedule is the fix.
For future reference: overwatering locks out calcium and magnesium uptake, which causes those rust/brown edge symptoms. It also restricts oxygen at the roots, triggering the downward leaf curl. Both resolve once drainage improves and roots dry out slightly between waterings.
Your plant looks healthy overall keep an eye on new growth to make sure the rust stops spreading. If it continues on fresh leaves, you may need a light CalMag boost to recover, but since she’s recovering on track, stick with what’s working.
The key lesson: watering frequency matters more than volume. Let the soil/medium dry to about 30-40% between feeds and you’ll avoid this stress entirely next run. You nailed the diagnosis and fix trust your instincts.
