The roots from the hightower (whatever that is) don't look good either.
They shouldn't be matted together as a rope.

is this root rot?

This is like I get in the tower
The plants grows good and the roots for me , looks good
Is not possible to upload MP4 videos?

Interesting, I've never seen such a gizmo. That would explain the long roots without any appreciable branching, as it looks like they have a ways to travel before reaching the nutes.
No, video isn't supported directly.

Looks like mold issues. Seen it before with transplant shock. Especially when not lowering nutes a little.

that's what i'm going with: mold/disease/infection/bugs. roots dont' look great but i dont' think that would cause those leaf issues

Look at the first root pic posted at 100%; the roots are in rough shape, they're almost entirely covered with the orange kiss of death. You can see some new healthy roots emerging but the vast majority aren't functional. The pythium clogs the root pores and is also what causes them stick together, not unlike plaque on teeth.
As a recovering long-time dwc grower, I'm quite confident the roots are the primary cause of his issues.

A boron deficiency in cannabis is relatively rare unless a plant is underwatered or in a really dry environment, and is usually accompanied by other types of nutrient or pH problems that appear as problems with the leaves.
The first signs of a cannabis boron deficiency is abnormal or thick growth tips along with brown or yellow spotting on new leaves.
With a boron deficiency, upper cannabis leaves display abnormal and/or slowed growth. Growing tips may not grow properly, may display twisted growth, and may die off. New leaves may wrinkle or curl.
Plant roots can also be affected by a boron deficiency, showing unhealthy or slow growth. Stems may become rough or hollow. Boron deficiencies are more likely to appear when a plant is underwatered or experiencing very low humidity (very dry air).
A plant with a boron deficiency may look like it has a calcium deficiency because boron is needed for the plant to properly use calcium. New growth is affected the most, and may look like it’s been burnt or scorched. A boron deficiency is often accompanied by an apparent potassium or nitrogen deficiency, as these nutrients are needed for the plant to use boron.

i'm with ya. i've had root rot issues too. but i've never had a leaf die from the base upwards like that. rot, for me at least, looked like normal nute lockout w/ burnt tips from the roots not taking in nutes as normal (overfeeding essentially)
@Rblade has this plant ever been outside?

if it was a boron issue, wouldn't thousands of other Lucas/ GH micro users also have the same problem?

I have uploaded more photos of the hydro tower where was placed the most affected plant
You can see the same boron def.
I think is not pythium or another fungi because the roots smells very good, fresh and healthy.
I think that the problem was my 5liter bucket. Very small for a 6 plants, and I run per 6-7 days, so the level of water is very low and maybe the nutrient solution became toxic or weak. I never measure PH neither. But I have never seen problems before in this hydro tower.
Maybe the stress of the change from the tower to DWC have it's weight too.

I've not seen a leaf like that either. I did notice, the times I had pythium, that the symptoms were weird and not consitent. I've had plants look otherwise healthy (for a while) but simply stopped growing, to having some where all new growth was twisted/spiraling. I think once the roots are compromised, it can manifest itself differently.

No. Because it's my problem. I have never seen this problem in years. But few weeks ago I run very low levels of water and nutrient solution. So maybe this became toxic, PH fluctuations , or very low quantity of boron. I think that was a mix. I never measure PH .. etc...
I think that with a few days or weeks the plants will be ok!

hope so, good luck

The plant I posted with the orange pythium roots didn't smell either.
It very well may be a Boron issue, but only because the roots are infected with pythium.
You might want to reconsider checking pH if you're gonna have success in dwc.
Essentially, nothing else matters if the pH is out of whack.

I have seen the new sprouts and seems healthy. So I think that can be good news.
I think is not pythium because:
- the plant was very strong and old
-I never have pythium in the hydro tower
-I have root problems in kratky and the colour, smell, touch.. feel different.
These roots smells fresh and healthy, not fish or frogs like, not slimy, not weak..
So I think that fortunately it's only boron and maybe pH problem.
In a week I will post with the results!

hope you are correct. how do you plan on adding more boron? or do you think fixing the pH will fix the boron defic?
What's the temp in your reservoir? Add some Calcium Hypochlorite to your res unless you have a chiller that holds it at 68F. I started in NFT rails and I left them because I was unable to reduce the reservoir temps without a chiller and there was no way I was running a reef chiller for some pot in California where my electric bill is insane. So I'm guessing it is root issues r/t to high heat and fugitive peroxide. But if it's Boron let me know how you fix it or find what fixes it. I'm curious!

You are using jacks soo it has all the boron it needs fix your ph.
And your plant is too small to fill a 5L bucket i had bigger plants finish with no problem you just have to give it 3L every day when it starts drinking like crazy

Chances of a Boron issue is almost zero. Best odds are roots issues. Probably just barely holding off the rot.
