Hello All,

I am newbie in hydroponics, I have setup DIY DWC hydroponics and below are quick questions, kindly help me

My plants are 3weeks in cycle and mostly vegetable plants like tomato, pepers, okra and others

1. what should be the ppm for 3 weeks plans
2. if the ppm is low can i directly add the nutrients with proper measurement or should i change all the water ?
3. If i need to change then i need to recycle 27gallon of water, what is the best way to do it
4. also any tips in maintaince would be a lot helpful
