WHAT IS CAUSING MY LEAVES TO CURL? (Day 64 pictures)
The leaves at the top of the plant seem to be curling up. My first guess is that there is too much light. I recently moved my light down to 12 inches above the canopy. The PPFD should still be under 1,000, but I don't know what else could be causing it. Please help. 🙏

I'm having an issue with two of my plants, the leaves are curling upward right at the base of the leaf. My humidity is right at 57-60%, heat goes fro 76-81 during the day, watering once a day. Does anyone know what might be causing this? Im on day 10, by the way.

Necrotic spots
The last day or two I’ve had a bunch of necrotic spots pop up on the lower 3 sets of fan leaves. She is at node #5 now and starting to put out pistils. Is this phosphorus deficiency? I changed the res as it was close to a week anyways. Thanks all for the help. Happy Growing!

This is a 27-day auto plant. The problem is that the leaves are crunchy and curled upwards. Soil pH measurement 6.5. There was a fan right in front of it, I changed its direction 1 week ago. Do you think this is a disease?

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?

Leaf tips on all my grows turn upwards slightly. I'm using a 260w HLG Quantum board LED light which is about 2.5ft away from the plant and temps never get higher than 27 degrees with about 60% humidity. Could it be calmag deficiency?

Starting to fade? Or nutrient deficiency?
One of my plants has several fan leaves that are turning yellow/purple, and I can't tell if it's low on N or starting to fade. The plants are 2 days into week 5 of flower with a 9-10 week flower period, so it seems a little early for it to be turning colors like this.

Heat stress? (1st grow)
Hi, Here we start with the problems. The leaves are curling up (little yellow), not much. I've looked that up and it's probably heat stress? -My led lamp is at 55 cm -The plant receives 500 PPFD Also a friend told me to water it nearly 1l, if that's the case I was giving way less

Upward curling leaves
Yesterday applied heating mat bcs temp was dropping to 14C nights. Now it stays 30C allday with RH 30%. I have found my seedlings looking like this morning. Leaves look dry. Could this be the excessive heat shock? Or soil dried up quick? What should I do? Water? Raise RH? How?

Starting Training
I'm currently worried about my older plant set that seem to be constantly having the leaf edges curl and seem to be a little droopy and a little too dark green. Also I feel like I should be doing some sort of training. I would love to have some feedback on what you all think. ✌️

Let it grow or cut it out?
One of the seedlings isn't doing so hot. Should I just start a new seedling in it's place or give it more time? I've had a stunted seedling like this before in a previous grow and it ended up yielding a lot...
