Heat Stress?

Ok so here's the deal. I got 12 plants, 4 misc. seeds, 5 Great White Shark and 3 Mazar. 1 of my Great Whites looks like it is suffering from a bit of heat stress while the others are flourishing. Each strain is cared for as needed, but this one plant just looks like it's got it bad.

Anyone have any suggestions? would be appreciated and may even get you a lil +rep

The last pic is a Great white Shark right beside it to show the difference.

Yea maybe a little bit.. just keep temp below 29°C (you'll have to do the math.. im european.. )

can i get some rep for that..? plzz

You want me to give you rep for telling me I may have a little bit of heat burn without telling me why that plant is getting burnt but the ones right next to it are fine.. It's not even directly underneath the grow light... and still it's plenty far away & the heat at the canopy is 86F.

You haven't told me anything that I didn't already know.

No REP for joo!

U see... reading about this kind of problem found that it could be many things... heat... water...nuts...

Started a thread to find out... but no comum ideas...

I think I could be the heat stress maybe....86 F are nearly 30C which is like growing cannabis over the equator line...

Im having the same problem but didn t realize that the box was too hot and humid (28C and 69%)...

Also, I have AF plants and they are 60 days old... into flowering... It could be a lack of P and K... to much N ( I did some foliar feed... but just one got the issue... dont belive it was the case)

Some guy said it was over watered...with is not my case...

So... as an expert grower like u... u probably did the basic check-list... ph ... temp... moist... vent... and seems a mistery.

I intent do buy an EC tester to make sure all is doing fine... but until that... just wondering...

DO the tests... stay closer...

How old are yours? Is it weel vent? The ph is correct... as u say... u planting diferent strains... and It may be the difference...

Post some pics of mine to make sure we have the same problem.

Lets keep talking... cheers

It COULD be from the fan... since the lower leafs are normal looking... I moved the fan and turned it down a notch. We'll see how that turns out, thanks for the comment I didn't really consider it.

+Rep sir

A couple of my plants right now are doing the same thing as the one in your photos OP. For me it is the heat from my HPS bulb. During the day the temps hit 86*F but I try my best to keep it around 78-82. I would move the light higher a bit (not by much) for a couple days to see if your plant recovers.

They were planted in soil on 9/25, vegged them for 3 weeks and then put them into 12/12. Thought I was going to have houseguests but apprently they won't be coming now, so time to get some more seeds
