Thanks so much for the reply! I figured the plants were using up the nutes so I kept adding , mixed with a gallon of water..... In 3 days , I lose about 3/4 gallon of water.Happy to see a new hydroponic post. Sorry bout the little fried plant. But don't despair.
It is good you are keeping the PH in a good range. It's good to let it bounce between 5.5 and 6.5. You don't have to keep it exact, moving around in that range lets it absorb its range of nutrients it needs.
Avoiding burn should be fairly simple. You just need a 15$ TDS meter. Something like this

With this you can figure out a safe concentration and just not go over that.
20 ml of grow every 3 days sounds way to much for little ones like these.
You don't normally add nutrients to DWC buckets directly. It's not like your plants are absoring them up at some fast rate. Nutrients actualy usualy get absorbed slower than the water. Meaning big healthy plants will drink a bucket of water down while the PPM concentration will go up.
So instead of adding more and more nutrients to the water in the DWC bucket over time, you will let the plants drink the water down, and top it up with fresh water to dilute the ppm back down to desired amounts.
I'll usualy add fresh water 2 times before I need to add a nutrient solution again.
How often you empty it all and start with all fresh water/nutrients is a matter of some debate. Some do it weekly. I like to do it after I've topped up my 5 gal bucket with 3 gal worth of top ups.
Little plants like yours will probably drink less water then evaporation. So they really don't need to have water/food solution added often. Just keep the ph/ppm where you want it and the water level steady

Would you recommend connecting all the buckets to a central bucket , to cool the solution and add solution when needed ? I saw another system like that , but it wasn't a bubbler. Not sure if that makes a difference or not.Okay, this is not near as bad as how I read it. I thought you were adding in 20ml undiluted to the existing water. But again usually you need to top up twice with fresh to one time with normal strength nute solution. But once you have the ppm meter it will be fool proof.
Nute's are NOT FOOD. They are needed in small amounts, more like vitamins. Light is the food.

Right now , it turns on at 5 am and off at 11 pm. I want to change it so tomorrow the light turns on at 6 am and off at 10. Do this until the light turns on at 7 pm , and off according to whether it's in veg or flower mode.....
Can I do that ?
Thisremove it all and start over fresh, even rinse the grow media their in with freshwater and toss the runoff. may have built-up salts on it.
your good no light no real demand on o2 from the roots. You have a whileWellWe just had a power outage.... How long can the plants go with no bubbles ?
Do I need to need rig up a 12 v air pump some how ? Been with no bubbles for about 15 minutes...
Thanks ! Normally they're back on in less than an hour , but we are having heavy storms at the moment.... If it's not back on in 30 minutes to an hour, I'm gonna go buy a 12v live well air pump....
