My PPM has been higher in runoff than the feeding water so I flushed the plants with PH balanced water. Water went in 200 PPM and came out 800 PPM. Is this bad ? What would you advise? I’m planning to flip to flower in a week. Veg week 5 CoCo grow
Your runoff WILL be higher, it's just a question of how much. These numbers hold better context over time than just spot readings to spot fluctuations.
