Question:

Would you prefer to eat once a week or each day?
What's better for you?

Plants have some flexibility but are not that much different.
2x a week with low light is okay, with higher light, 3x a week is about the min without having to pay a penalty in plant health/growth. Many do it daily and might skip a day or two etc.

The other issue is that they adapt to a particular concentration and as long as it stays somewhat stable over a range, then things grow best.

This is why you can have low levels and dose daily or high levels and get somewhat similar results although it's much larger and easier target to hit and allows 2-3x week vs daily.
