answered grow question 7y ago
Leaf tips curling up are an indication of LED burn. I’d suggest trying to raise your LED lights.

Top leaves turn dark and curl - What can I do?
I've had Nitrogen and possible Cal/Mag deficiencies 2 weeks ago. Mid last week I started noticing some burn a the tips, so i dialed nutrients back again. By this weekend the tips of the leaves curled further and turned dark. The rest still looks a bit pale, but buds look good.

It looks like my plant is dieing! Plants turning brown after intense watering period
Did I drown my plant? Stress it? I gave a lot of water in a short duration of time, and now 7 days later she is looking terrible! Read my diary on week 17 for more info!

What do I do about this fungal infection?
Follow up to my previous question. What do I do about this infection? It's fungal. I have crop defender 3, but the plant is starting to lean because of the weight. Help?! She is also killing another set of large leaves. And she's healing, I think, but it's taking too much time.

Leaves are looking a bit strange.
Leaves looking sick hope its not root rot, i changed the light but only from 25% q5 to 50% evo 3 maybe it was a bit too close. I tried closer to prevent them from growing more in hight.

Anybody got any idea with what's going on with these 2? The 2 larger plants are showing the signs of some stress on the fan leaves. Oddly enough the runt of the 3 is not showing these signs. Has anyone seen this before or can help me identify it?

Sudden Leaf Yellowing – Lighting Issue or Something Else?
Hello! Yesterday, I noticed the top leaves turning slightly yellow, but today it looks dramatic. Check the pictures—leaves are yellowing and drying out rapidly. It’s only affecting the central leaves, so I suspect a lighting issue, but I’d like to confirm before taking action.

Leaf Curling - Late Flower
Growers, Small issue. LOADS OF LEAF CURLING. I assumed it was nitrogen so I stopped all nitrogen for 3 weeks & no fix. Flushed with 20L of water thinking its possibly salt? Nope still got a curling problem. Any ideas why this is happening & is it a big issue with 3 weeks left?
