Ouch
oh brother no way
the spots look like PM 🙁
get out the hydrogen peroxide start pullin them leaves off and start hittin ur stems diluted so it doesn’t spread
the curl may be heat stress dude or a nute problem
its a P problem bro…i study cannabis and im 99%
Didn’t read ur comments yet, but seeing the one leaf, I can tell you, you used too much bloom, just flush the plants that show it with PH 5.5 water. The second to that is heat. But I don’t think that’s a problem you got fans. Peace.
Make ur pH betwen 5.5-6.5 ! An exccess of Fe and Zn could make the P unavailable.
Flush with clean water (left opened 25-30hours) 3 times more than the soil in the pot – so 15L soil flush with 45-50L water ! than add a fertilizer with more P than N and K ! hope they recover ! peacE !
probly a nute problem. I have never used hydrogen peroxide on a plant… must read up on that
Many thanks again for helping me grow the best medical weed! This is another example when the comments are more valuable than the video!
no good, hope you get it figured out soon. Will be watching for posted updates about this. Sharing this video in case others might know what’s going on
I;m glad to hear that – I feel sad when i see unhealthy girls – what ever the reason is – i fucked up 10 times at least – maybe more – thats how you learn – but always read more comments – cause there are people who talk shit on purpose – and people who talk shit unknowingly ! peaCE !
yikes! White Powdery Mildew!! I’m onto the H2O2!
just add more of your bloom nutes and that should do it, but first flush out the plants and then add your nute again but with extra bloom… the plants love phosphorus especially when they are flowering so its kinda hard to give them nute burn by adding more phosphorus… i just went threw the same problem 2 weeks ago and got it fixed by doing this…
It could be too much light or heat, but if it happened overnight, (then Im assuming the lights were off,) and it could be too much air blowing on them or too much humidity to make them curl to expire. It could also be a nute problem with too much NPK or maybe not enough Mg, but if you haven’t done anything new with nutes, than it could be too much water. If its too much nutes, flush them, if its too much water, let the dirt dry out real good b4 next water. Good luck!
Hey bro the captain is right,those spots thats white powder meldew,sorry bro,hope you dont depend on this grow,tsg peace.
So awesome to have #cannabis #growingtips from the best weed growers on Youtube! Many thanks for the details THC Sacrament – you and Capricechild92 make me, and my girls, very happy!!
I’ll be going with straight water for the next couple feedings… what should I do to get the Phosphorus corrected?
nice plants bro… but what you have is phosphorus deficiency. hope this helps:D
From what I’ve learned, some plants just don’t need or like nuits. I had lowered my lights one time and the same night forgot to drain my pans after a heavy water. Root temp plummeted, canopy got warmer vented all the moister in the leaves to stay cool and bam DPD lock. I was told to leave the leaf material on and the plant will naturally take from it what it needs before dropping it. I truly hope your bounce back. Mine did but delayed everything for about 3 weeks. Peace!
BTW we are big fans!
I just had the same thing. I believe it is either VPD (Vapor Pressure Deficit ) which can happen if your plants get too hot on top and the roots change temp too quickly or you have lock-out/lock up from over watering. Eitherway, raise your hood to minimize further lose of moisture from the leaves and flush then pray a bunch. I hope it works out for you. Peace.
ya if you dilute well you can kill that PM off
a few people I know have used that suggestion and had 100% sucess
The heavily spotted plant was moved from one DWC bucket to another, and the Dieseltonic had just received a watering with strong flowering mix… both actions caused big stress! I flushed the potted plant, but never thought to check the water in the DWC bucket… Very good questions! Thanks!
Yeah could be PM. I live in dry hot so never a prob for me. I wouldn’t add nutes. Maybe cal,mag to water but hey comments can help.. the lemon juice tip was horrible, left an ugly film on the leaves, not pretty. Lol peace. Stay green and hope u figure it out eh.
excellent! my #marijuana is looking better already! thanks!
I didn’t know what PM was – White Powdery Mildew – THAT is alarming, and worthy of instant action!
Thanks Derp! I removed all the curly leaves and flushed the soil with straight water… This plant is Desieltonic, and I’ve had trouble with it before… very sensitive plant!
Thanks Vincent! I did just that. Two gallons of ph corrected clear water… let’s hope tomorrow morning brings better results!
I would say flush for few gallons and not feed for week when you go back to feeding them drop nutes back to about half or so will be watching peace
what is the best way to boost Phosphorus without stressing the other nutes?
id get a grow bible and look it up they looked like they didnt agree with some nutes you added but you need to look at your own setup and see when they started to stress. did you add anything to your nutes? has your temp changed more then 30 degrees in a 24 hour span? did it get too dry or humid in the room? trace the steps you used and see if there is anything different
remember… when in doubt, flush them out.
