Its been a complete year now and every single grow churns 100 % sick plants. all different, quality strains . first few grows I was noticing PM. But at this point the PM isn’t manifesting itself, only the other common symptoms. right into Veg the leaves have a rubbery look and feel, if i cut off a leaf and bend it, nothing snaps at all. The leaves are green however they have a powdery look starting on them, however it doesn’t wipe off. If i took photos they wouldn’t show the true story. The only option I see at this point is to stop for a long while, ive been wasting so much time, money, and effort on plants I always end up dumping is a shame . I have let the COCO dry out between all grows and, used everything from h202 ,sulfur spray, milk, nothing effects this. Feeling cursed, as far as growing goes, has anyone had a similar struggle?
Are you using an ultrasound humidifier with tap water?
Soil should be left to dry out between waterings. Coco should not. If coco drys out it becomes hydrophobic and will no longer absorb water. Coco should be watered daily.
It’s hard to help a whole lot without pictures that show the health of the plant. Pictures will tell us more than you think they might. You will get both more and better feedback when posting pics.

You’re growing in coco-coir and multiple grow attempts have been unsuccessful?
Or every grow attempt has been unsuccessful?
How far along do they tend to make it before you decide they are toast?
I know you said pictures wouldn’t show the whole story but they could very well help us figure out how to help you. Any pictures you have is better then none.
Could be many things but if ya don’t care to go through a bunch of questions I and many others will do what we can to assist you every step
Every single attempt has been unsuccessful for a year now. As soon as they go into Veg I can start noticing the plants turn totally “rubbery”. They might even be green but they are limp. Im feeding jacks, in sure thats why plants look outwardly healthy, they are getting nutrients but whatever this is its insidious. Has anyone had a night mare like this, what one do to exterminate a disease like this?
Every attempt in coco-coir?
Fresh coco each time or reused?
I have an idea that while it maynot tell us whats going on it could maybe get you a harvest so you at least have a successful grow.
I’m all about coco-coir, i grow most of mine in coco-coir but sometimes I have 1 that just gets off to a rough start in coco-coir and I just put it in soil with tons of good microbes and many times it finishes out fine.
It’s just an idea but try one or a few in fresh soil pre-loaded with this product or one like it.
We can certainly continue solving the coco issue but if it’s something getting into the plant via the substrate thats just infected your area somehow, the microbial life in soil could possibly out compete it no matter what it is until you figure it out.
Pictures worth a thousand words
But almost equal to filling out the support ticket above as best you can.
Help us with those things so we can better help you.
Where the rubber meets the road
Every grow in Coco. I reused the coco, from what I understand once the plants are gone spores should clear away, I am not a scientist and theres alot of mixed info out there so, i have no idea what is truth. But yes I have reused the coco after letting it dry for weeks after each unsuccessful grow.
How about filling out the Support Ticket and providing recent pictures.
Reuseing coco is something alot of people do including myself a little bit.
After each grow before the next it needs to br washed and/or rebuffed a little bit to kinda insure its free of any leftover salts from previous grow and its ph is stable.
I fill my pots up with coco-coir and I add just enough calmag (or any veg nutrient would work) but i add just enough to get ppm about 100 so i can ph that to 5.8 and keep pouring it through each pot untill the runoff is coming out at 100ppm and 5.8ph so it matches whats going in.
Sometimes it doesn’t take much and sometimes it takes alot to get the coco-coir washed and “reset”.
Was you doing something like this in-between or just letting it dry out?
Also is this just straight coco or is it mixed with something like perlite?
Hey @THCMaker44 powdery mildew possibly. What nutrients are you using? coco coir is inert and you should keep it damp so water daily. You can include vermiculite to increase O2 in the coco medium. Lots of things to consider and a short lesson from Dr. Bugbee would tell you a lot about grow essentials.
You’ll get various answers so watch this and fill out a support ticket so we know what you’re doing. Also include full and closeup pictures in white light so we can view them girls.
Wel getter done. Happy Growing!,
Coco coir has no Silca in it. Silca will strengthen the cell walls and helps prevent Powder Mildew.
. Hydroguard will provide you with beneficial microbes and make a world of difference.
I found this on the web about using Yucca extract as a wetting agent.
Yes, you can use yucca extract in coco coir to help it stay wet. Yucca extract is a natural wetting agent that can reduce the surface tension of water and make it easier for the water to penetrate the coco coir. According to Coco for Cannabis, yucca extract can be used to make the fertilizer solution and water “wetter” by reducing its surface tension and thus assisting the plant nutrients in penetrating the root zone more quickly.
Found this using Chat GPT-4, minus the links of course.
Yucca extract is a natural wetting agent that can be used to reduce the surface tension of water and make it easier for the water to penetrate the soil ¹²³. To prepare yucca plant material as a wetting agent, you can follow these steps:
-
Harvest yucca roots: Dig up the yucca plant and remove the roots. Rinse the roots with water to remove any dirt or debris.
-
Peel the roots: Use a sharp knife to peel the outer layer of the roots. The inner layer is what you will use to make the wetting agent.
-
Chop the roots: Cut the inner layer of the roots into small pieces.
-
Soak the roots: Place the chopped roots in a container and cover them with water. Let the roots soak for 24-48 hours.
-
Boil the roots: After soaking, transfer the roots and water to a pot and bring it to a boil. Reduce the heat and let it simmer for 30-60 minutes.
-
Strain the mixture: After simmering, strain the mixture through a cheesecloth or fine mesh strainer to remove any solids.
-
Store the extract: Store the yucca extract in a clean container and refrigerate it until you are ready to use it.
If you prefer to use a commercial yucca extract, you can purchase it online or at your local garden center.
If your having the same results every time using same coco coir as your medium it’s possible that when you purchased something was wrong with it from the supplier. If you elect to send pictures and a solution isn’t provided I would start fresh so you remove all possible contamination. Check your nutes for expiration date etc. Cover all your bases so you can ease the pain and you can finally enjoy the grow. I’m sorry your having issues I know it must be a huge weight on your mind. Send pictures this community is awesome with a wealth of knowledge that can help over come issues.
John the plants look good, this issue is barely noticeable unless you look in closely in person. Or, like I said cut off a piece of the plant and try to bend snap it. Seems as if the plant is drenched in oil. NO snap to it if you bend it. PLEASE go bend any of your healthy plants!!! any part of them!!! its going to snap, you’ll hear and feel it. promise
Again, feeding JACKS 321, its not expired, using Canna, its not hydrophobic at all, it soaks water like a sponge. Yea i will dump the coco this time, and the fabric pots i have. I just dont know if that’s enough, and just how long can this disease/ or spores can survive in the room, after the plants are gone.
There is a disease, mold, and its extremely Virulent

If this is the case all you can really do is trash the coco-coir for sure, bags to if ya want or wash them good in vinegar water then run them through the washer and drying like clothes. Viniger, full wash cycle and then the dryer, they will come out sterile
Then just try and clean your grow space the best you can. Many options to “sanitize” any anti mold or mildew cleaners or mix up your own from h2o2, bleach, vinegar, the diy options are endless.
I use straight 3% h2o2 and just wipe everything down the best you can and cross your fingers.
As far as "how long can spores last in the air or area " who knows. Im no pathogen except but I imagine it depends on exactly what it is and not knowing that, its impossible to say.
I’m curious if along the way was the ph stable at 5.8 throughout the grows and plenty of runoff each feeding
Ph being out can do some really crazy things to plants.
They can grow full cycle and all kinds of weird stuff can happen and they can develop it really strange ways.
5.8 to 6 for sure. Im in coco so I always PH the water. New coco sounds like a last thing i can try, thank you for reading/ replying Happ Papp!
