Outward Edge Curl
IrishGrowsstarted grow question 4 years ago
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?

Generally, cannabis plants prefer temperatures in the 70-85 °F (20-30 °C) range during the day when lights are on. I do not see any issues with your plants they look healthy to me, watch getting water or nutrients directly on your leaves during lights on, you may want to try a bit less water, also the humidity at 20% is super low, young plants, seedlings, and clones like higher levels between 55%/70% - Try a little less water, get Humidity up - and Temps Down a bit. You are doing great!

Slight lightburn?First pair leaves on left plant turn slightly lighter, first sign of yellowing a bit. Also I think they are a bit in a V/praying shape.
2 full weeks old under 75% of 200W leds about +-45cm. Should I dim them a bit more/hang higher?
Other suggestions maybe?

Leaf Troubles: Nutrient Overload or Calcium/Magnesium Deficiency?What’s happening with these leaves? The tips are curling up, and the DLI is below 45. I’m unsure if I’m overfeeding nutrients or if there’s a calcium and magnesium deficiency. What do you think the issue is?
Please help me, I need to feed in a few hours.

End of Flower, Yellow and crusty leaves ok ?Hey last weeks of flower and I’m not sure if it’s fine how they are developing, as I started flushing this week they quickly started developing yellow crusty leaves.
Should I keep flushing them as I will cut them in 1 or 2 weeks or should I try to balance out missing nutrients?

Problem with plants in the 3rd week of vegetation.I'm posting again because I accidentally marked it as resolved.
I was using BioBizz CalMag from the beginning, but when I switched to Advanced Nutrients, I stopped because Ph Perfect Sensi Coco Grow A and B already contain CalMag.

2 autos with crispy feeling sad looking leaves, how can I help them? (more info in diary pl & crit)2 of my autos have been growing leaves that feel crispy and look deformed. I have been watering when the top 5 cm of the soil dries, but I fear maybe I fed them too much nutrients. The temp has also been on the high side (30C 80F). What could be wrong and what can I do for them?
