Hello so i have been having an issue with just one plant curling leaves up on the side. I lowered temp check ph checked under microscope checked my run off my run off was very high so gave her a light flushing until the ppm droped below 800. Nothing i did seem to change anything. Someone suggested i looked at the roots which is a bit of a pain so it was my last option but now i think i found the culprit. A forgotten plant id stake was pressing up against the side about an inch below the surface. I also noticed that i didn’t center the plant when potting it before and that could have been part of the problem. I’m repotting it now too a slightly bigger fabric pot.

The taco is usually a sign of light to close or to bright.

Right, that was my first thought i got a PAR meter though and it was only getting about 30 dli should be getting closer to 40 to 50 the bigger one is getting like 33 I’m taking the reading from the very top of there canopy so most of the plant is actually getting a lot less I’m going to gradually increase it once i know for sure it was the roots. The lights about 14in away from the canopy and they are in week 8 growing in coco ph is 6 temp is any 72 to 78 in the day and night 65 to 75 i did bring the temps down 2 to 3 degrees and lowered light intensity from 80 to 60 from when i first seen signs. Humidity is 40 to 55 during day and night is 50 to 65.

Seedlings – max of 48 inches from canopy top. Vegetative – Between 35 and 48 Inches from canopy top. Flowering – Between 21 and 39 Inches from canopy top.
Ill keep my seedlings super close to the light. Depending on the light source. I use t5 bulbs so they arent super intense.
What i used to say was 18 to 25 inches away from source. The internet says from 12 to 40 somethings. Thats depending on light intensity.

That’s sure going to be a lot of trauma at that late in flower. Best of luck. It sure looks like a good portion of your roots are dead. I would soak the root ball in a bucket and let most of that wash off by gently swooshing it around, then put it in fresh coco.
Best!

The plant is effed this late in the game tbh, best thing at this point is to put it in hospis. What I mean by this is whenever you mess with the root zone of a flowering plant it stresses them out to the max, its only going to exacerbate the situation, also the root zone looks extremely dry, if the plants aren’t getting enough water for a given vpd and the lights are super intense an overly dry root zone cant cause issues ultra quick as the plants wont be able to transpire effectively or at all.

I’m far from giving advice… but if you mean the slightly raised tips, then I’d be happy to have your problem 
… @prey and to all the experienced growers here, please correct me if I’m wrong… does this look like slight light stress?.. the leaves have a tacky shape and the points are already slightly drawn towards the center of the leaf… more a question than a guess…

The roots look way too dry, where the plastic was on them they look healthy as the plastic helped keep the water from evaporating as fast, just my two cents…

Thats exactly why i stopped using coco. It dries out to fast and you always have to be messing with cal mag. And i dont use those cloth pots because there shit and you dry pockets that kill your roots and if you let the coco overdry it really hard to get it evenly wet again. I have 150 of those cloth pot out in storage in my green house thats how i know they suck because i used them for years. Now I only use promix hp as a media and plastic grow bags. I run Rwdc hydro and auto pots and traditional hand watering all my mothers. I start all my clones in an aeroponic cloner and then go to hydro or promixhp.
If one plant is having issues just let the leaves taco. Its not going to hurt anything. And trying to do all you can to try and fix it is a pia and its probably not going to change anything. I get some plants that taco and some dont. I run expensive lighting equipment and i build most of my lights and i have a photobio par meter. And i still get tacoing leaves. I just ignore it because its never affected my yields or flavor or anything for that matter. Some plants just taco under certain lights. I bleached buds completely because of too much light and i didnt have any leaf tacoing. So that right there showes me that the light being too bright or too close to the plant didnt cause tacoing. So its really hard to say whats really causing it. And trying to look at the roots on a flowering plant is not a good idea. Because it can damage more of the roots and dry them out stunting the plant further. Id let the taco plant just grow. And if it bothers yiu take a clone and reveg it and grow it a second time and see if you make it grow better and not have taco Leaves. I have a haze plant that hermied a little bit and i cloned it to try and grow it again. This time to see if it was just my fault and not the genetics or if it was light stress.

So i already had transplanted it to a bigger fabric pot should i take it back out and soak it or you think it will do more harm than good right now since it’s already in there’s? I’ll have to remember that if i ever have to do it again. It’s on a much less brighter light now also

Id leave it be. Just make sure you do a couple waterings. Like water it a little bit let it soak in and wait like 5 mins and water it some more. And let it soak 5-10 mins. Come back again and water it.
Question: do you ever water run off? Coco is harder to manage and the cloth pots also accelerate the coco drying out!
Also coco can get pretty saturated and still contain 20% air. So there is less if a worry of over saturation. But get it to wet and its hard to dry out properly. But id water it a bit in stages to make sure its thoroughly saturated and water it. I used to bottom water in those cloth pots and seemed to really help. Maybe get a pot saucer and bottom water soak it kinda soaks it up also!

I have a drip system i was doing 30 min every day is co co and dries fast but i started doing it every other day and just been pouring extra in when it runs… I’m going to need with the lines a bit 1 plant is about half the size and needs alot less so i was going to add 2 more lines so 2 have 2 lines and short 1 has 1… when i repotted that plant i let it dry for 2 days so it was easier to get it out

I noticed this and I do this from time to time. Also different coco mixes have different water holding capacity (WHC). I’ve played around with different mixes and like the 60% ones best. agree with everyone above just baby the plant and leave the root zone alone.

Ive grown dwc, soil, coco. Leaves taco from the lighting. I currently am running 400 house plants in coco mixes. Not a single problem. I am running 150 watt t5 8 bay lights. Not tremendous par but Enough to keep them happy. They have been growing in it for over a year now.
I do water every other day. Some plants everyday.
Dakine coco 420 and dakine 420 lite. They are blended coco mixes.
I took it out of the tent with the big light and put it in the small one… i think it may have been the side lighting doing it i didn’t take readings from the side facing side
