No idea what's going on with these leaves

Hi all,

I got a set of leaves from one node on a plant looking funky; some of the leaves have curled and crisped up, and there's a few leaves with a light discoloring. these discolored areas also feel thinner but softer, like velvet. sorry all, I'm a bit high, this might be irrelevant/nonsense..

any idea/experience as to what might be causing it?

I have two plants going right now in the same tub, both "Lemon Shining Silver Haze" (seeds from royal queen), in hydro. Everything is dialed in (more or less, i'm not perfect), but I'll try to list as many details as possible:
- Using GH Flora Nova Bloom (so following Lucas)
- DWC hydro: water temp at 68F, using a chiller
- Air temp: 75-78F, RH: 60-70%
- LED light: currently drawing about 170W (it's a prefab, blurple unfortunately); have grown two rounds with the light, and even though it was overpriced, it definitely works
- Other things in the tub: microbes and silica

Thanks! pics coming from my phone in a second

I'll chime in to bump your thread to the top.
I'm not a hydro grower. I love the length of your roots but the color, not so much. The pictures are good you should get some help soon.
I'll enjoy following. Good Luck

Thanks! I definitely need it...

The brown color's from the nutes, so I then realize it's hard to tell whether I have other root issues causing further browning. It's the GH flora nova bloom, the stuff is dark

The damage you see on the leaves is due to root damage or pathogen. If you don't have any root pathogen and roots are not slimey getting mushy and color is for sure just from the nutrients. Then you may have had something that has now passed and new growth will be fine, or it could just be the beginning. The leaf issues is 100% from root issues, most likely a pathogen. It is no nutrient deficiency.

(One thing I suggest is that you gradually drop water temps a few degrees cooler to the 65'F range. Don't shock them and go too cold too quick, but get it and set it there if you can. Will be better. Water holds higher dissolved oxygen levels at lower temps and pathogens have much harder time growing even if present.)

Thanks for the tip, just went ahead and lowered my chiller down a few degrees (now set at 64F, which should get the res to 65 by tomorrow). Using a cooling coil (wort chiller) that's sitting in the res.

The affected leaves have gotten worse, but it doesn't look like it's spread to any new ones. The other plant in the tub seems to be fine. I'm also not getting a smell or any slime from the roots or the res, but I'll keep an eye on it.

Pics coming from my phone in a moment. I just tied the plants down so it's hard to tell, but the affected branch has stunted, basically isn't growing compared to the other branch, which I even snapped a few days ago..

The way it has only taken hold of one branch of the plant, this points exactly to a root issue, like for some reason a section of roots is dying off, or pathogen has taken hold and not yet spread to the entire roots and plant may be fighting it off.

For example, a big tree outside, or any plant, if you cut off certain section of roots, then a certain section of foliage/branches up top and only a certain section will die back. Roots below feed different plant parts up top and are directly connected. The plant adapts quickly, but root death equals top growth death. something is goin on down there, for sure man. physical root damage by mistake at some point, or pathogen.

how many Mls per gallon are you mixing the floranova?

drop your chiller temp down to 60

hygrozyme might be a better option than cutting the roots

Thank you all! All makes sense, that it's a root issue. The plant in question has gotten worse; is it even worth trying to save the other plant? Like, should I try removing this problem plant?

Other leaves on the affected plant have begun to show the same issues - getting thinner, flimsy, and losing shape.

pH has been between 5.8-6.2, and I only have a TDS meter (for which I don't know the conversion...) but it's been reading steady at 450 ppm.

The plant hasn't been moved in 3 weeks, and it had grown fairly vigorously when I did = I'm almost certain I didn't damage the roots recently. and sigh, I feared this day was coming, just a little sad it came so soon. This is only my third round in DWC

Look into what Satori mentioned, hygrozyme.
Also look at SM90 and H202

All 3 I have used over the years, all work great in their own way for this type of issue.

These things can make roots shiny white healthy again killing and eating away dead and diseased shit
H202 will increase dissolved oxygen in there also small amount for short time after application.

Cool, I've heard about hygrozyme, I'll order some now.

I like how trying to minimize the number of different nutes/supplements has backfired tremendously lol, got like 8 different bottles already

Growing in DWC, you almost always have to use some kind of root protector like the hygrozyme. p.s. you can use the hygrozyme at 1/4 what it says to. Works just as good, but while in trouble root times, may want to use at full strength this once though. From all the bottled things out there, Hygrozyme is a real good one. Works well.

Ok, I'll work on diluting the nute levels for now. Also added another dose of hydroguard and myco, figured it wouldn't hurt.

I do see that a portion of the roots are white, and another portion is pretty brown.. leaves are looking worse.

Funny thing is, the other plant is looking pretty good above, but its roots don't look any better.. hoping for the best I guess
