Robertsanswered grow question 5 months ago Looks like you have a week to 2. You could start your flush now. You were running pretty strong nutes as the plant is showing burn from it. Flushing is not bs. If you are doing organic, then you would not need a flush. If indoors using any nutes, then I would flush. It improves flavor and quality. In your case with providing high nutes prior. I definitely would flush.
