Looks like it has a little heat stress, but still very healthy looking for being in high heat all week.

Yes light heat stress but nothing to worry about. Mother nature has always taken care of herself outside.

Curling new leaf growth, slight yellowing.I’m getting some strange curling leaves seems to be upwards. It’s only on new growth and I’m seeing a more yellowing color around the tiny curled leaves.
It could be light burn, heat or humidity as the only thing of change over the past days is a random spike in humidity.
Thanks

Otherwise healthy leaf curling in on itself at top of plantAnything to be concerned about? This is a plant that has had a history of yellowing leaves due to I think nutrient deficiency. New leaves are coming in light/dark green. Maybe caused by being too close to the lights? (It is my shortest plant with about 1 ft distance)

Seedling leaves are discolored and starting to curlNot sure what the issue is here. You can see it evolving over the past few days (Sept 29th - Oct 2nd). The leaves are discolored, light, almost yellowish in color. And one is starting to curl. There are clear images of this in the post above. What's going on here? Thank you!Leaves. Curl up

Phosphorus def in veg?Phosphorus deficiency in wk 4 of veg? I noticed a few small discolored blotches on lower leaves 2 days ago and today it is a lot worse! Use flora trio, and 2 other plants in this run are under same conditions with same nutes. Could this be a pH issue? PH has been consistently ~6.

Strange leaf deformationHave these strange leaf formation on some of her blades, looks liker the main vein has somehow outgrow/stretch, with no actual green stuff around lol. Several leaves have this. Combined with a slightly general canoeing, could it be from a nitrogen tox ? Growing good though

Rusty Leaves3 upper fan leaves have "rusty" brown spots on the upper side. Hard to spot, hard to capture on camera.
I also have slight "clawing" on many of the upper leaves.
Mg/Ca lockout because of nitrogen toxicity possible?
Doesn´t seem to be fungi, as there are no spores to rub off.

Heat stress? (1st grow)Hi,
Here we start with the problems. The leaves are curling up (little yellow), not much. I've looked that up and it's probably heat stress?
-My led lamp is at 55 cm
-The plant receives 500 PPFD
Also a friend told me to water it nearly 1l, if that's the case I was giving way less
