Look along the branch part on the underside of the leaves with at least 60x magnification, they bury themselves in there .. after reading ur post I looked at mine and I'm pretty sure I have the damn things as well

Update
So the other day my heaters did not show up and with the plants looking worse by the day I decided my fish could live a few days with out theirs.
res temp now sitting at 72
I still think it’s spreading. I left a few of the affected leaves on they have become dried and crunchy to the touch.
i plan on going through and trimming out all fan leaves that are showing these issues. I didn’t want to further stress the plant but the leaves are dying anyway so don’t see much benefit to leave them....
The more I look at the plants I’m realizing that it has really spread. I’m seeing early signs on most of the leaves.
this really sucks
Ph dropped to 5.5
Ppm raised to 700
Topping off res today with plain ro water about a gallon or so

Ppm was 640 after the top off.
I removed all of the plagued leaves and any other leaf that looked suspicious.
Definitely don’t think it’s insects or a nutrient problem, light, water, exchange, circulation, reservoir or vpd.

So that leaves fungus right? I’m thinking if it pops back up I’ll hit them with southern ag spray? Idk still researching

Honestly they just look like they are over fed... can be many contributing factors. VPD, nutrient ratios, genetic needs etc. Im thinking dial back to 450i-500ppm.

ppm at 700 with ph at 5.5 should not cause this. Did you redo your rez water and brought the calmag down?
i know you said the roots look okay, but double check them. i've got a feeling this is a lockout.
I just found this online from another site and thought its very nicely done.

Nice, love a good chart.
I did a change out the other day, Calmag was Added at 110-120 ppm
No flora gro added with this res change only bloom and micro. 5 grams of epsom for 10 gallons total. Roots look ok. Don’t smell funky or anything... kinda smells like a fish tank
thought it might be rust fungus but nothing wiped off the leaves when rubbed
After looking at the chart I’d say it’s a calcium deficiency but I don’t think that’s the issue. I’ve been very consistent with the calmag throughout this entire grow. I’m always between 110 and 120 ppm
