So my second soil attempt (first looked great but got pollinated halfway through) these are a few days since the lights flipped. I watered yesterday, I sprayed zerotol for the last time for some safety measures with humid colder nights and I’m thinking these plants are showing me signs of overwater, or something with the edges of these leaves curling a bit. I do not think the lights are too close,I checked with the par meter, hottest it got in there yesterday was probably 79. Really hope this doesn’t become bigger I can’t have this right now. If I over watered soil in flower like this are they gonna be fucked?
The last picture shows that one plant has 2 fan leaves with the tips pointing down like this but that’s it I’m not sure if this is that the light was too close or over water. I hate mornings like this, I love when I walk in and everything’s looking great lol now im just gonna be trippin till they look better. And not the good kind of trippin.
are you adding any calmag product?
What’s RH? Temp?
i had a girl crush do this a bunch. i think it had a root zone issue. when i would give it calmag it would get better for a short while then return to this. in flower it was okish, didn’t eat too well, but gave great buds. the problem may go away at some point as it did with mine. if you have your environment under control and the feed is normal, what else can you do but wait. if it gets worse, perhaps take it more seriously.
I would too also like to know. I have a plant showing serated leafs with slight curl. Im thinking over watering i have been trying to water more often lately which i never did before
In my experience, leaves curling up is usually due to light issues. The plant is getting more light than it wants and is trying to reduce it its exposure to the light by curling up its leaves. How did you check your PAR? Unless you’re using a proper PAR meter I would take the reading with a grain of salt and look to the plants for answers. Dim your light, she will react quickly if that’s the issue.
Def not overwatered, they will curl downwards and look droopy. If anything it would be heat or excess light but your temps aren’t too hot at 79 so probably a tiny bit too much light. Some plants roll up the sides and taco from genetics as they flower but that usually happens on sugar leaves. They look healthy tbh. Leaf curl sometimes happens with vigorous growth as well.
Just looks like they got too hot/close to the light…
But you’re saying highest temp was 79? Is that much higher than usual? Or was that sustained constantly?
79 shouldn’t be too hot, but if they were really close it could still cause the curling edges. Usually plant will curl like this when it’s trying to retain moisture, not when it’s over watered.
I recommend this app too, even the free version is great for an idea of where you’re at ppfd wise.
Could always by a cheap IR thermometer off Amazon to check your leaf surface temps. Another really good tool to have to dial things in.

Ok I’m responding to a lot that are asking I do have a nice apogee PAR meter. The readings are 500 around the outside to maybe 1010 on the inside highest point. One light over the more curled leaf edges is 15 inches up. The other light I had possibly too close I didn’t measure but I realized I had the light turned down to about 60% strength and still getting just under 1000 with the par meter in the inner points. I can see that maybe my temp gauge in the middle of the tent is not realizing how much heat could have been on the leaves from that but what makes me have a doubt in the back of my mind is that the plant with the more stressed leaves is under the light that’s 15 inches up.
With that being said there was a point with the lights too close weeks before with these plants and I saw it quick and changed it(life’s been hectic) could they have been a little sensitive with that still maybe?
What I need is a temp gun maybe to make sure the surface of the leaves isn’t too hot I’m thinking from what I’m reading thank you to everyone I usually respond to everyone but there’s so many coming to help i really appreciate it
If you end up grabbing a light meter with LED you want to be able to measure the Photosynthetic Photon Flux Density(PPFD) measures the amount of micromoles of photons striking a square meter per second (often written as umol/m2/s, μmol/m2/s, or μmolm-2s-1). This measures the total amount of P.A.R. produced by a light source per second Good luck
Edit because this didn’t mean to respond to anyone and don’t know how to untag lol
I think because I was trying to get a little less heat by turning down the lights and putting them closer, I may have gave too much heat to the plants? Gotta make sure I get a temp gun to test specific spots
This is happening on one of my plants aswell. Serrated leaf with slight curl. No clue whats the cause i was thinking over water or too much light? Running a 450w led on dim mode set to 25% and about 3ft from canopy.
You can monitor micro environments much better with the IR gun. Highly recommended. I think you nailed the issue, lower light out put but being physicaly closer to the plant causing higher heat on the leaf surface causing a micro environment situation
