Hi. Sorry about your mishap. Happy to help you figure it out.

Can you describe in careful detail:

What were symptoms of plants before they died ?

Wilting,browning,yellow, twisted etc.

How much were you feeding?

How close to top was water level

The leaves look really healthy in this picture. And then the main big family started getting brown spots and a little bit of yellow and curling a little bit down. I will post pictures

Once the roots started coming out of the rapid Rooter plugs. I lower the water an inch below the net pots. I’m using the three-part micro grow bloom from Advanced Nutrients. Using the instructions as they say on the bottle

You can see the slow decline from week three to right now I will show you the plants right now

How many ml per gallon of each ?

Ph to 5.8

Go lower on water level 2 inch below bottom of net pot.

Is there plenty of air from airstone ? To little air can suffocate or drown them.

That’s rite now ?

If so looks like drowning. Lower water level as stated and check air to airstone.

Are you measuring EC?

I asked about water source. Following manufacturer’s recommendations with an already hard water source can easily lead to a complete lockout.

The bottle instructions say 4 ml per liter. I had maybe two gallons in there. I probably put 4 ml of each one of the nutrients. That’s way less nutrients Then instructed right? I must read it wrong. I don’t know how to read the EC levels. But the PPM or at 290-390. I’m guessing the PPM levels being low like that is because I put way too less nutrients than instructed I’m supposed to put at least 16 to 20 ml for 2 gallons I’m guessing. I just got a stronger air pump to get two stones in there I thought the oxygen levels were also low so I’m working on that. I had fungus gnats and I’m sprayed them with an organic oil. And I’m using distilled water for everything.

Ok. Keep the ppm low at this stage. I’m usually around 150 to 200ppm.
The bottle will prob show max.

Google feeding schedule for the nutrient brand you use.
Should find a nice schedule that explains how much to use at each stage of plant life

The brand that I use is the three-part micro grow bloom from advanced nutrients. And the instructions say 4 ml per liter. And I have a 2 gallon Reservoir. Doing the calculations that’s from 16 to 20 ml. And that’s giving me my ppm’s around a 1000 should I lessen the nutrients?

Yeah go way less. You will burn plants with that much.

Need to find someone who uses that brand to get a feeding schedule.

How often were you making a complete reservoir change?

Every week.
