Possibly a sign of low humidity, leaves can "taco" as a way to slow the rate they loose water by decreasing their surface area. What is your RH%?

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.

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.

Weird leaf
It seems one of my leaves has become very oddly curled up. It has very slight brown spots with a strangely curled up tip. As seen on Week3-day19. Can anyone identify some sort of problem like excess or deficiency of nutrients?

Rolled in leaves and kinda pale and started to curl up
Leaves have started to curl up on day 5 and down look that healthy, so I have lowered the water level, raised the ph to 5 and doubled the distance to the lamps, did I do the right thing?

Why have the leaves on my plant turned pale and crispy?
4 weeks into veg with auto and all of the leaves (including new growth) have turned very pale and dry, starting at the tips and receding rapidly. I’ve used the same two part nutrient solution in the same quantities as I did with the previous same auto, so Disease maybe?

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?

Brown spots, serrated edges curling up - calcium deficiency?
This is a Barney's Critical Kush auto that's at about day 57. She's into flowering, but I've just started to notice some brown spots on leaves with some slight tip browning, and the serrated edges on the leaf are curling up. Is this just a straight calcium deficiency?

Nute burn or something else?
I’ve had a few leaves shrivel up and die on this turtle taffy. 2 feedings of FF Grow Big so far, less than recommended for light feeding even on both feeds. I did notice a lot of morning dew yesterday, this plant took longer to clear it than my other two

Leaves curling
I notice some leaf curling and also have some holes. Is it an issue? I raised the lights up a little as they were down below 20" i want to some defoliation but not sure where to start or if getting rid of big fan leaves and small leaves at the bottom will stunt growth

Strange leaf deformation
Have these strange leaf formation on some of her blades, looks liker the main vein has somehow outgrow/stretch, with no actual green stuff around lol. Several leaves have this. Combined with a slightly general canoeing, could it be from a nitrogen tox ? Growing good though Cheers
