Diagnose this leaf issue, wrinkly and a bit of tacoing?!

Smokenpassout · Monday at 5:56 PM

Just curious what this girl is slightly suffering from? She looks nice and green. noticed this in the past couple days. She’s been on a light nutrient dose of under 1/4 strength and about 30 days old. She’s a little strtetchy so I brought her height down a bit by taking off her base. Could it be the light intensity stress? She is small only 5 nodes, so I have the LED 24” over her at the 40% suggested.

Looks fine to me. Id worry more about flipping having enough room if youre already having to remove a base unless it was really tall. I use cinderblocks.

I agree with @medidedicated. The leaves have great color. OTOH, pictures of the entire plant and grow area are very helpful.

24" and 40% - what light are you using?

What’s your humidity and temp?

Good question.

And wind speed-fans blowing on the plant might be causing the leaves to curl.

I’ll follow up with another for OP. Are all plants in your area doing this? Or just this one? If so are they the same pheno (clones)?

No , Id call this one the runt of the group. Different strain than the other three which are 3X the size in 30 days. others are nice and short and bushy. This one is healthy yet tall and lanky.

Could be wind, I have my lower oscillating fan set to 3 of 10 and giving the plants indirect movement for 18 hours a day along with light. I could kick it down to super gentle at 1 or 2 .

The led light is an AC Infinity Evo 4. Full Spectrum led, 3X3 space.

Looks like heat stress. I had heard that the new aci leds had hot spots. Can't remember where I read that, so don't fact check me. Maybe check the leaf temperature to see where you are at... or just let her roll, she looks fine.

If this is the only plant doing it then make sure something in the environment isn’t directly hitting it (fan, humidifier fog..)

Other than that I wouldn’t worry about it and bet it grows out of it. Nice and green

"hot spot" as in temperature?

I've written about the "hot spot" in terms of the PPFD map but LED's generate so little heat that I'd be surprised that anyone even measures temperature.
