Should I add only water to reduce PPM/TDS?

[Tosmtt]

Hello

When the plant use the water in DWC, the PPM/TDS get high, should I add ph'd water to reduce it?

Thanks,

Are you using an enzyme, in your nutes?

Hello

Sorry I don't know what do you mean by enzyme, I am new to growing. But I am using:
- Botanicare Hydroguard
- General Hydroponics CALiMAGic
- General Hydroponics Flora Micro
- General Hydroponics Flora Grow
- General Hydroponics Flora Bloom

thanks

that means your starting PPM is too high. it should be dropping along with the water level.

 

[WinterSoldier89]

Its the water level

 

[rkymtnman]

Its the water level

what's the water level?

 

[WinterSoldier89]

Your water level is going down, that will be why your ppm is going up.

 

[rkymtnman]

Your water level is going down, that will be why your ppm is going up.

wrong.

Ok what then?

see post 4. if water is dropping, ppm rising, ppm is too strong. in DWC, i like to see water dropping and ppm dropping daily. that means they are eating and drinking normally.

so in @Tosmtt situation, add RO water to the res to get the ppms down to a point where they are going down daily.

When I ran NFT I always replaced my reservoir weekly because I wasn't sure what nutrients the plants used and I liked to keep a stable ratio. I also would try to get it so that my TDS and water were close to equal. That's the sweet spot.

that is the holy grail of dwc for sure. i always felt more comfortable if my ppms were dropping somewher in the 10 to 50 ppm range per day. reassured me that they were eating.
