already said but once a wk n they stay happier easier.no more than once every 2wks(imo)..u will c best growth rates doing it wkly.as for ppm check it ea day for 3-4days,if there drinking more then 50ppm a day then u can up the overall value slowly.dialed n wud b tech no drop n ppm over the 3-4days.but i like to c a 10-20ppm drop a day,just so u kno there drinking nutes.but if u get to point where ppm raises over them few days yur too highHow often, or at some level of ppm decline?
Twice for the whole grow.if your shit is right you won't need to
Just my opinion but the whole purpose of dro is being surgically clean..you get that clean dro taste from rezi changes.y let it sit n same water diluted down multiple times..basicaly same concept of dirt then n my eyes.just my opinion
The plants drink most of the water.being chilled the older water actally stabilizes the ph so far less ph swings.if I was not on a chiller I would probably change every weekI understand this concern but I have personally read a number of threads that have stated this does not happen. Of course if you have other issues you can have problems but not from solution changes or lack of. I'm talking about people who have done it a multiple of ways and found not changing at all had no effect. Of course you still need to run plain water at the end to washout the nutes fron your plants but why would you have to wash them out multiple times?
That's right.not sure how you would keep temps at 68 without a chiller.As long as your temps stay around 68 or so you should be fine? If you run a chiller or not?

plants don't choose what they eat at the roots lol.thats like saying there like a kid in front of a plate of food.what your saying is simply false.if plants got to choose what we gave them than we would never burn plants.they take in everything that's available.this is why we increase p and k during flower and decrease N so that it is less available.When you leave the water unchanged, every time you feed you're adding more NPK to your res, if your plant uses all of the N and P but left some K then next time you feed there will be an excess of K. If you let these imbalances continue then things can go downhill fairly quickly.

Nutrient change outs in recirculating DWC is NOT necessary if everything is in check.Plants take in alot of water that are healthy and receiving the proper amounts of light.This water contains the solution and goes into the plant growth.Plant growth does not come from thin air.It comes from the water and the nutrients in the bottles.A well tuned DWC can go an entire grow without a changeout.I change mine twice during the entire grow and have never had issues with anything.As a matter of fact i think you do more harm than good shocking the plants with change outs every 2 weeks.My plants get balanced and stay that way.
I have these plants going now and have changed there nutes once so far and that was when i transitioned from 1 to 2 ratios.they are in a 14 gallon system and drinking 2 gallons a day.so in 14 days they will have drank 28 gallons of nutrient solution.That is twice the amount of the system they are inMe changing out the solution would be defeating the purpose.It would be throwing away money for nothing when the plants are drinking twice the amount of the total volume available in 2 weeks.Once i stopped shocking my plants with change outs are started getting healthier looking plants.But it also requires a fine tuning which i explained my technique in perfecting scotts OG in my sig
