Leaves curling up after changing from HPS to MH
Skunkman420started grow question a year ago
I've had a question answered regarding leaf drooping due to overwatering/adding feed too early but now I've changed my bulb to a 600w MH the leaves are curling upwards. I've turned it down to 250w for now it's currently at 45cm above canopy level.Any ideas? Thank you ☮️

taco leaf, to much heat and or to little humidity.
Might need to raise that light up a bit more or dim it if possible. If you don't have a fan going it could also help.
Good Luck!

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.

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?

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.

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?

This margin curl appears to have spread from one plant to 2 of the other 3. So I assumed not pH, not lockout, not nutrient based. Roots all great. I've culled the 3 and there is 1 survivor doing well but what was this? In the diary I mention using Temprid FX, Neem, Spinosad.

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?
