plant problem

Hi all

Quick question, can anybody tell me what this is on the leaves?
It has been very hot so found it hard to keep temps down, i’ve averaged about 34c last week.
The top leaves were praying a bit so i’ve been moving lights up and getting the fans blowing a gale on the top canopy to try and cool them down.
Do you think this could be light stress,
heat stress, wind burn or something else?

Any advice appreciated.

to me it looks like a little too much of something in your soil... if it were me I'd dilute my feed for a few days and see but that's me

i’ve been feeding 1/4 strength nutes and only gave them the first dose on day 22, then 2nd dose on day 27 and 3rd on day 33. could it still be too much of something?

I can see what bigunyun is seeing ,some clawing but im seeing th edges/ serrations curling which says heat issue. Could be windburnt too if you have a " gale" blowing on canopy

This almost looks like a fertilizer burn.

Thanx for replies guys.
Also found a few yellowing leaves on bottom of plant.
Any ideas?

You should really keep those leaves attached..
They are a food source for the plant..

Gonna say ….. Semen .

Do you sleep walk without pants ?




J/K minor spotting probably from fert.
lower leaf ( especially 3 finger ) will go bye bye anyways over time ( plus its touching soil surface ).
Plant looks way over nuted ( nitro ) - Dark coloring / tip claws.
