Looks like heat stress ,if your light has a dimmer try turning it down some. If no dimmer then raise the light if possible.

Leaves curling up and color changing, is that normal?
Hi and TIA, So this last week some leaves at the top of the colas started to curl up and the color change to something a bit more yellow with spots on it... I want to believe is normal given she is close to the end but I would love to hear the experts opinion?

Something is definitely wrong. Any tips are welcomed (be gentle lol, I’m not a professional). Nutes or lights if you had to guess? Does anyone grow organic? I’d like to learn more about that. Where do you get your seeds from? Do you like auto flowers? Tips from start to finish?TY

Leaves curling upwards
What could this be? I consider too intense lighting, could that be possible. Just transplanted a few days ago into these 1,7l pot's. Since it is the first time i use the The Mars Hydro TS 1000 for flowering i think i might have given the plants too much light.

Spotted crisp leaves
What's up with these leaves? They've all been spotting up, crisp edges and tips curl. I keep flushing them and it helps. I feed them 1 tsp calmag to each gallon and often the mixture gets diluted as much as half. PH water was 6.2 but soil 4.5. 15" from 70% light.

Outward Edge Curl
Noticing an inward curl to the outward edge of leaves. Happened before any nutrients. Temperatures for the tent have bit 78-94 with some times sticking in the low 90s for hours. Have been able to keep the tent in low 80s the last few days. Anyone else have a suggestion?

Too Much Light?
Top looks yellowish, more so IRL than in the pic and the new growth is kinda taco-ing. Just under 24" from the light, 78F and using Photone the DLI was at ~30. I don't really trust that app but if it's even sorta accurate, 30 might be high with no CO2? says their charts anyways.

Twisted, yellow/brown tips.
Hi, My plant has shown signs of a nutrient excess throughout its complete cycle. It keeps to the tips of younger the leaves that have a tiny twist in the end. I don't think it's the light as it also affects leaves in the lower canopy. I keep on flushing but nothing changes.

Serrated leaf edges curling up a bit with no discoloration. Have tried cal mag foliar spray, raising light, flushing with water (ppm just over 500 runoff from flush). She doesn't look unhappy, just wanting to make sure she stays healthy! TIA!

Leaf problem
My leaves are looking strange? Can this be because the leaf hasn't fully unravelled/grown fully yet, or could thus be heat/nutrition. Added 2x pictures to see clearer 😁

Small yellow spots
I have small yellow spots on leaves. I want to say it starts at tips and travels down. I moved light away and it seemingly gotten better. I moved tents for bigger space and it might have returned.
