Yeah It's on a timer. They're definitely getting the water they need, and they sit on drain tables so they aren't soaking in the runoff. Ppms are reading slightly higher than what's going in, which is typical when I check runoff ppm Looks like there's deficiencies of some sort creeping in, but the way the leaves look are weird, I've never seen any this bad. I pulled the plant out of the pot and the roots are nice and strong. No foul smell of root rot. I've dealt with it before in DWC so I'm familiar with how it looks/feels/smells.I'm assuming your automatic watering? I'm really not sure about this. I'm kinda learning myself. But are you lifting the pots at all and making sure your soils actually absorbing the water? I was thinking maybe hydrophobic.
My dude I answered damn near all of those in the initial post but I'll make it easier to read my bad didn't mean to come across as an assWhat media?
pot size?
watering frequency?
watering volume?
ppm and PH input and runoff? (actual numbers please?
light make and model?
light distance?
temp and humidity? (Day and night if possible)
have you seen any bugs?
the better info you give the more reliable and easier the diagnosis
That’s what I was gonna askhave you seen any bugs?

You got the coco god's attention. Got to do some work for him.My dude I answered damn near all of those in the initial post but I'll make it easier to read
Have you scoped the underside of the leaves?My dude I answered damn near all of those in the initial post but I'll make it easier to read my bad didn't mean to come across as an ass
What media? Coco
pot size? 1 gallon
watering frequency? 7 times a day every two hours
watering volume? 30% runoff
ppm and PH input and runoff? (actual numbers please? 500/650
light make and model? Floraflex 645w led 800ppfd
light distance? 2-3 feet
temp and humidity? (Day and night if possible) 84 high 70%. Vpd 1.1ish
have you seen any bugs? Mild fungus gnats
Yeah I haven't seen anything looking thru jewelers loupe, I did have some thrips that came with the clones I got. I sprayed with 3 different brands a couple days apart, but that was weeks ago and I haven't seen any since.Have you scoped the underside of the leaves?

My runoff is 30% of medium(1 gallon pot) throughout the course of the day (typically not this high, just trying to get a little more runoff to see if there's an issue in the medium).runoff 30% of what? How much are you putting in?
you ppfd is waaay to high for the health of those plants. What light cycle are you running? i would be dropping ppfd down to like 200-300 until they recover… if they do
slurry test is no good. Do you know the runoff PH. If not please check next feed.
if your seeing fungus gnats you have a bunch of larvae in there eating your roots. Treat with BTI for the larvae and yellow sticky pads to catch the adults.
wgat are your leaf temps? (if you have an IR temp gun)
lower your temps to 76-80f for now.
is this a sealed room or vented? Tent etc?
your VPD is likely off quite a bit. You have to take leaf temps into account. Its likely less than half what you think it is. Drop the humidity to about 55-60% with room temps i gave you.
there is a lot of work to be done here fixing things. And not just a single issue. If you want to work on it then read these to help you understand some of why and what i asking these questions for. These 2 you need to know and understand.
HOW TO WATER COCO FOR BEST RESULTS.
Ok writing this cause i see this issue often and rather have a thread to link than explain this each time. This is not my work but a collection of info from many members here and I have put into practice myself. So first off COCO is NOT soil. For best results we want to keep it saturated...www.thcfarmer.com
VPD (vapor pressure deficit)
Ok i was gonna sit down and write out a whole article but i have been lazy so instead instead I'm going to copy paste because im lazy. This is not my work so let start. You may find this very long but its worth the read. Some may want to skip ahead. I have added here and there to what i feel is...www.thcfarmer.com
LED is usually about 3-4f lower but can be as high as 10f if they are transpiring a lot with lots of air movement.My runoff is 30% of medium(1 gallon pot) throughout the course of the day (typically not this high, just trying to get a little more runoff to see if there's an issue in the medium).
Ppfd is probably high, just odd that I run it this high in late veg before I flip to 12/1300 but I do agree that it's likely that high and I've turned down the lights and temp as of yesterday.
Runoff is anywhere from 5.6-6.0 depending on the plant. I also have a bluelab probe that measures rootzone ph that is giving me the same readings.
I dose bti once a week.
I have a flir camera, leaf temps are 2 degrees lower than room temp.
Room is sealed with CO2.
I'm not sure how my vpd is less than half of 1.1 but 70 Rh/84 room temp/82 leaf surface temp comes to .98, which should be fine for veg right? Unless the calculator I use is wrong or something is misleading in my inputs.
Idk either way I appreciate the input. I'm hoping the lower ppfd and temps will help though. Would be ideal if that was the issue
Yeah, I was under the impression that was normal, I had no idea surface temp should be that low.LED is usually about 3-4f lower but can be as high as 10f if they are transpiring a lot with lots of air movement.
So your leaf temps are as high as 83f? thats a problem. They should be around 75-77f most strains show stress around 79-80f
in my 1 gal coco i was feeding 250 ml and looking for 25ml runoff. Dont need to measure every plant.
you adjust the feed frequency based on the runoff. Not sure if you have a timer capable of seconds or if your hand watering but 30% input is very high if its working for ya great but if you putting 30% in and getting 30% out there is a problem with uptake and judging by the plants thats possible.
