That is generally a symptom of heat stress, try lowering the temps if you can.

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?

This girl is the only one in the growth tent (she is with other 3 strawberry cheesecake auto plants) with leaves curling up. The lamp to plant distance it´s at 80 cm, and the wind source its not hitting her directly. Could be overirrigation?

Why are some leaves curling strangely?
Hello everyone, the problems begin unfortunately. Why are some leaves curling strangely? I have not given any nourishment, the temperature and humidity are constant, will it be a problem of PH or EC? Thank you in advance.

Orange leaves getting worse
What the fuck is going on with this plant? I spotted some nute burn last week so I got advice off here and flushed it out. Once it needed watered again I went with half the recommended nute dosage and now it looks like it’s getting worse. What the hell can I do?

What's causing my brown crispy leaves!?
Over the past week my plants have taken a turn for the worse. Many leaves went from yellowing to browning to completely crispy! Other leaves have brown spots on them and some of the stems are purple.

More rusty spots
See this now on more and more leaves. Only upper fan leaves that get good light exposure seem to be affected from this and also the clawing. Have backed off the nutes completely for now and will add ground egg shells to the water in the hope its a Ca deficiency.

Week 6 flower HELP
Leaf tips curling but not discolored on my bubba kush. Had some pH issues last few weeks but finally corrected it. They weren't like that yesterday, it was 74 when I opened the tent today. What could it be? Is it a big deal?

Is this nute or sun burn? What should I do to save my babies ?
I upped the nutrients to week 2 of veg state (biobizz) and put the light to 50% intensity. I put the light at 6 inches above recommended height (which is recommended on the Mars Hydro website for beginners). . IS THIS NUTE BURN OR LIGHT BURN?

Brown area on leaves
Bonjours à tous. Voilà certaines feuilles de ma plante deviennent attrape des tâches brunes. J'ai donné du GHE essential (oligo-éléments) and cal magnifique (0,3ml/L) ce matin ainsi que du biographie Bloom. Je pense à une carence en magnésium et vous qu'en pensez-vous?

Nute burn (Added nuts to supersoil)
So, I added unnecessary nutrients to my super soil and end up with nute burn, I Flushed until ppm was 1100 it was over 6000, and since i've been dealing with yellowing and curling leafs, brown spots and well it's all going down so quick. Any idea how to fix this. I'm lost.

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?

One of three plants curled its leaves.
One of these three seeds seems to have suffered a bit, but unsure why - the conditions have been pretty much identical from what I can tell. The first set of leaves curled quite significantly but the new growth seems to be ok? Any ideas?

Crispy leaves?
Crispy leaves developing as it flowers. Seems to just be those that had some spots from what appeared to be a magnesium deficiency. I hit it with cal-mag and the spots stopped but recently the most affected leaves are shrivelled. Only maybe 4-6 leaves right now.
