Sooo hot out!

[Theonewhocooks]

I was curious if these leaf burns or crispy ness was from a heat wave we just went through, 105-110 for a few days… any help is awesome

thanks

I would say yes... Even Old growth trees on my property got stressed and my wife had a lot of damage in her flower garden... 109f

What have you been feeding them cause to me the look short on nitrogen and high on flowering nutrients as if you suddenly switched nutrient regimes?

 

[ct26turbo]

Did you water them during peak sun?

 

[HydoDan]

No, you don't want to water in the heat of the day..
Sun rays get magnified by the water and burn leaves...
We always water in the mornings but with those temps we watered again after sunset..
At 3:00 -- 109F.... At 8:00 -- 68F... The fog moved in!!

Lol ya those lazer beams burn up all the plants on earth everytime it rains! Hahaha.
Lol. Water isnt going to make magic lazer beams and burn your plants. I've grown outdoors for many years and have yet to see a plant go up in flames from waterdroplets.

Usually cloudy when it rains.. Not a human adding water to plants on the hottest day in history.. DF

Cloudy when it rains then it's sunny again. I've seen it rain and be sunny at the same time. Lol. Water droplets don't burn plants
I do agree with you adding cold water to the plant on a hot day could shock it. So best to water in am and in eve. But if the plant needs water then water it.

I douched my ladies daily with the tap from the hose, bags too, they loved it at 97°.

My canopy will hit 105 and consistently runs over 100 until October. My plants don't look like that. I'm with @Herb & Suds it looks like too much Potassium in the first picture. The other burn I've never seen before but it doesn't look like heat burn.

 

[twentyeight.threefive]

Yeah Whatever

It's ok to be wrong.

You know I'm not sure. If you read that it says smooth plant leaves won't burn but plant leaves with hairs might. I think about Cannabis and it's sessile trichomes and I wonder. So for me I simply don't know. It's a definite maybe in my book! Worse cannabis that's smoother might not and those with tons of hair and trichomes could.
