Heat Stress?

Ok so all the plants in the tent seem to be healthy and happy and then I have this ugly duckling. Think it’s a Sativa so more probed to heat stress. I have the led 300w about 24” or more above the plant and it’s getting nice circulation. Not sure if it’s strain related or not. Comments.....
I am adding another 4” exhaust today and adding another fresh air intake. This I think will solve any heat issues

Going to guess that you know about ph and all that, looks like possible nute burn and then light/heat stress after and ph may have been what started the process?

Yeah I always feed and water with ph at around 6.5-6.7. This little plant has always looked a bit pale compared to the other plants. It’s only bag seed so I’m not to concerned and I have a few extra plants lol

She’s definitely more fussy then the other strains when it comes to heat. I’m dealing with the heat today. Two 4” exhaust and two 4” fresh air. I am waiting to buy an infinity T6 but right now I’m using what I have right now

Looked at your pics again. Is the affected plan in back left corner? If so it may be wind burn from the white fan just above

Ya I’m in the process of rearranging and setting up the space a bit better
