No. If she is eating less or more, the numbers will be different. Every plant eats differently, makes better or worse use of the existing stuff in the soil, etc.
This is likely an issue. I won’t say it definitely is, but watering til runoff is one of the most important steps to helping prevent salt buildup in the pot. If you’re only watering enough to get the pot wet throughout, it’s not enough to allow the expended nutrients/salt buildup to wash out of the pot. The more salts that build up, the harder it is for her to uptake the beneficial nutrients.
