Green Crack

@Willy_Wonka24,alright ! I do a flush last week of Veg , flushing them at the lowest right level , otherwise when they go and get that Nitrogen for the stretch (whatever the amount of salt in the media) if the media is to salty ( hypertonic conditions) the cells release their water to return the system to an isotonic condition (to get the same amount of salt on both sides of the cells), and instead of water flowing from the root to the fruit the process reverse and the roots actually start draining the plant, has the leaves edges and tips are the furthest away from the root this is why they start to burn , instead of sweating they reverse the flow has the same rate . P.S: Same when they need PK for the flowers
