First dwc grow need help

The biggest is 4 weeks others are 3 weeks old. I'm using general hydroponics base 3 nutes, cal mag, and hydro guard. I use filtered water and ph is around 5.8 ish. The person that was supposed to take care of them didn't do anything. one was almost out of water. This is them 3 days later any tips to help them recover?
4 week old farmers daughter the other 2 are 3 weeks same strain

About all you can do is give them a fresh batch of nutes and maybe keep the humidity up and even spray a little water under the leaves.

As the water levels went down the ppm probably got pretty high so I'd keep them on a medium feed schedule for a bit.

They'll be fine but find a better helper next time.

You got any pics of the plant before the person supposed to take care of it?

What are your roots looking like?

you didnt give much info looks like heat stress.was the water under the roots or what?
temps?
what are the ppms now and what where they when you left the plant?

Sorry yeah the biggest had maybe 2 inches of nute solution in bucket. Roots are massive and still white on all plants.
I did a reservoir change on all so they are all sitting in new batch of nutes,
I'm doing 7.5 ml of general hydroponics base 3 nutes. And 15ml of cal mag because I use filtered water
And 6ml of hydro guard
425 actual watt vipra led light
6 inch exhaust

I also need a suggestion on very good ph probe and ppm probe , I test ph with indicator solution. Temps stay below 70

I use apera ph60 and ec60 after breaking both my cheap pH and EC metres. To me the plant looks over watered which in hydro would mean not enough oxygen by roots?

It looks similar to my first plant I grew with a weak pump but idk

What would be a good pump to run all 3 currently each has its own but I want stronger

I don't really know too much about the air pumps I'm new to DWC myself but I used a very small aquarium pump like 4w at beginning and when I switched to 25w vivosun air pump it made a world of difference it was amazing.

I used to use smaller aquarium pumps that worked pretty good. Dual air line ones so I'd have one line from each of two pumps going to each of two tubs. That way in case one pump failed each tub would still have one 12" airstone working. Then I got a couple of these ECOAir commercial pumps and they really push out the air. The one in the pic is the smaller of the two and could easily do 4 tubs. I burned the other one out using it as an aerator pump for my dugout and the back pressure was too high. They are not quiet pumps so if noise is a concern you would have to make an insulated box to have it in when running. My grow room is down in a bunker under the house so noise is not a problem for me.

Very hot. Hard to diagnose anything else with the plants being so hot. Does not look like light stress, just extreme temps or humidity or both

3-5w per plant air pump.

What your roots looking like?

Sorry for no response they are looking amazing. I upgraded to a 45watt air pump. This is the first plant today, also they are starting week 3 of flower.
I'm 5'9"
