Noticed some deficiencies due to?

hey there Kevgrow, what happened is actually overfeeding as you can see from the burnt tips, this led to lock out which has the same symptoms as a deficiency, but you're flushing already which should help with all that. Nothing you want to be doing to there right now growmie, it's the last stretch before the finish line. Good luck ! hope this helps ! 🚀

Hows the humidity been? Did you test your PPM and pH runoff before flushing? Is that a water droplet that's yellow? If your PPM runoff was low, no need to flush.
