More Noob DWC questions...changing water? PPM?

[Chris1]

Hi guys, more elementary hydro/dwc questions (But I'll be a champ soon enough...)

Should I ever be swapping out the water entirely? Or am I just going to be adding water as needed?



And with PPM, should I be adding nutes/water as PPM fluctuates?

 

[Mr. Greenthum]

when u switch ur plant from Veg to Flower u will need to empty all the water and before u put new plants in u have to disinfect ur system i use 29% h202 with water then i give it a clean rinse with osmosis water. WARNING 29% H202 WILL BURN UR SKIN!
And u add nutes when u ppms are to low keep in mind when u add nutes u add water.
ppms range between 800-1000 and PH is between 5.5-6.0
