Ppm

How concerned do I need to be about my PPM? I grow in coco and maintain proper PH. ( most times) I checked it for my first time and it read 637. Thats with distiller water plus 5ml Cali/magic and 5ml of nute. Using humbouldt oneness. I also used ph up to balance. All four plants are in week two of flower. Is 637 PPM ok?

Ppm is nice to measure,if you grow this strain again you can see how strong you were mixing your solutions at what stage.
that way if you never burn your plants this run ,next run you can use slightly more and push it harder.


also if you burn this plant this grow,you will know not to let the PPM's get that high next grow

Yup thats a good PPM. keep increasing 50-100 untill you notice slight nute burn on the tips then back off. Or if your happy with what they are doing stay where you are.
