First grow feeding question.

How does the plant look? If the plant looks healthy, don’t worry about it 👍

Are you seeing any issues with the plants? Each plant has different preferences, some genetics can take the higher PPMS. If you have tip burn on your leaves - Great, don't flush, you want to push them to the edge of what they can take with Nutes. This changes week to week. Do you have dark leaves? Great! They aren't hungry... Do you have other issues you are seeing in them, then yes you can flush. It's not the worst thing to flush at this point - while it is a critical time, it's worth learning what it will do to your ladies. They might get hungry and lighten the leaves. but my overall advice is - Do less... just pay attention and respond to the plan not to your numbers... best of luck growmie!👽
