Problem with leaves in flower

limp biffskit said:

So one of my plants seems to have tacoing leaves. I've tried raising the lights and dimming them down aswell as raising the humidity they've been absolutely fine all the grow but over the last week it's developing issues.

I've tried to do as much research as possible to solve this on my own as I find it is the best way to learn this is my first grow so I'm still wet behind the ears. I'm running dwc canna a nd b nites 5.8-6.2 pH 1.2ec 20-21c water temps 50% humidity and 24c as of my before I was running 27c and 45%.

Mind the nute burned tips I had an issue with ec raising and pH dropping a couple of weeks ago

But as you can see there rest of the grow looks decent

Any help would be highly appreciated cheersView attachment 5460476View attachment 5460477View attachment 5460478

in late flower the tops of my plants usualy start tacoing and show sighns of heat and light stress as shown on the plant on the left but at this stage i don't worry to much as i know i am giving a them a good amount of light the tops of these two autos were getting nearly 800ppfd so a little to much for the fan leaves. your pics look similar if its not your lights it might be that fan is it blowing directly on the leaves? If so that could be the issue. I try to keep my fans blowing well above the canopy. You should get some good advice from other members with more experience and knowlege than myself. Good looking grow you have by the way. I think a few bugged leaves is worthy sacrifice for dense buds
