A quick explanation for those unable to watch the video.

With a double Dutch bucket setup there are two buckets on top of each other similar to SWCs. The top or inner bucket has multiple holes drilled in the bottom for nutrient solution to drain completely out.

The bottom bucket only has a hole for the nutrients to drain out of the bucket. So when the pump isn't running the growing media doesn't sit in the water/reservoir at all.

All around it is a very nice setup and I'm very happy with the results so far.

If there are any other questions fire away.
Edit :
I've added my thread url for some pics of my basic setup.

2016 brings an upgrade to the garden.
Concentrate tanks and a new feeder.
All from scratch of course. Because, well just because.

All data entry is through the encoder click wheel.
Set ounces/day per emitter and how many feeds/day and it calculates the interval.

The 5gal is the reservoir. It has a small submersible pump and a float switch inside.

When feeding the pump is turned on and the correct valve turns on for the prescribed time.
After the feed cycle is complete the fill valve opens and the peristaltic pumps spin at the correct rate as determined by the flow sensor in the fill line to make the nutrient.
Oh I can dial up or down ph and nutrient strength as well.
Dont really need it but can control nutrient addition to microliter level.
Daylight sensor causes feeder to turn off at night.
I think I will adjust feed interval eventually based on light intensity.
Someday will have wifi too....
Probably needs a neaten up and a box to keep the mice out of the electronics, but had to get it going in a hurry.

Wild bees on rapini flowers looks like they love them.
Hydroponic GARLIC! Its very tall, 3ft? bulbs are just forming, first scapes noticed yesterday. Stole a couple because I didnt feel like going to the store.....

Looks like I got 2-4-d'd again.
For the last week or so a very strong manure smell from the neighbors way, we are packed in pretty tight here. They are avid flower gardeners, and brought in a truckload.
Is it even possible for 24d to volatize from manure and hit my plants?
Funny its within a few days of the same thing last year.
Their beds are only 30' from my plants.
Doesn't look as bad as last year yet.

Fish lake is first to show signs.
Twisty tops, cobra heads, parallel veination.
Hard to convey how much this sucks.

Sorry to hear this Nematode.

Just thinking out loud -- Are you on well water? Could it get into the water supply or carried by run-off? I've lost an entire tomato bed to 2-4-d via manure but I unknowingly amended with a toxic load.

My county extension agent says 2-4-d is residual and can have an effect on sensitive plants for up to 7 years.

I re-used some coir bags from last year. The plants are just now aggressively setting their roots in that substrate.
It may be possible that last year the plants translocated 2-4-d to the substrate, and the new plants are in a growth phase that is very susceptible to the herbicide. I will try and identify the older bags to see if they are the ones showing the problem.
New coir bags came yesterday, and I have a few transplants left to try in them.
Thanks for your thoughts on the matter.

Nutrient issues could give similar symptoms.
And, do tobacco users touch your plants?

[Nematode]

PH my current nutrient (peters hydroponic special 5-11-26) is very low in boron zinc and iron compared to chem-gro. I have to supplement with fedtpa and run ph 5.7 or lower to avoid low fe symptoms.
I do suspect low B, or z. Low B in particular can cause twisty tops.
Chem grow is on the way and will try as soon as it arrives with ph 6.2.

No tobacco here.

Thanks for the input

Sorry about your plants. Hopefully the problem is nutrient related and will resolve with your nutrient changes.

I had a healthy Rosella Crimson do the same way when I brought it in and potted it up into a Itsy Bitsy Self Watering Planter(3 gallon). I let it sit without lights for a couple of days to acclimate. It looked terrible! The leaves were like sticks, they didn't curl, I don't think; but the growth slowed, and the new growth were tight, compact, hard little sticks. I thought it was a goner. I went ahead and put it under a cfl bulb, and after a couple of days, the leaves started returning to normal. No clue what happened.

[Nematode]

Its coming in the water or the air.
Not substrate related as new and old substrate plants show same problems. Also some yet to be transplanted still in rock wool are looking twisty.

I found this link, it looks like fe eddha a chelated iron (like sequestrine 138) has the potential to protect tomato from low level 2-4-d exposure. Reference is a bit short on details, but not much to lose at this point by trying.
Might have to get some and give it a test.

I hate to see this happen again have you talked to your neighbors about it.

[Nematode]

They would be horrified if they caused this, they are good folks. Have to find a way to ask what they have applied without accusing. I just know I haven't applied anything here. This is a second home for them, Ill ask next time I see them but won't call.

[Worth1]

Yeah something like, "I am thinking of using so and so on weeds, have you ever tried it?"
