Looks like it has a little heat stress, but still very healthy looking for being in high heat all week.

Yes light heat stress but nothing to worry about. Mother nature has always taken care of herself outside.

Leaves curl up and yellowing
Beginner question, as usual (first time growing anything in my life tbh). My 2 plants don't look too healthy, especially one of them. Leaves curl up and yellowing (or not, I am not sure). What am I missing? Thanks!

Nute burn in late flower
I've encountered some late stage nute burn and have brown and twisted tips on fan leaves as well as some bronzing. I am reading different treatment options for nute burn online but what else should I try at this late stage? I flushed ph'd water w/calmag and it's slowing a bit.

Some leaves curling up. What could that be?
Hello growers!! I've got a worry here. Some leaves are curling up. Room temp is 26°c, RH is 70% and leaf temp is 24. VPD is perfect for that stage. Watered her yesterday ph 6.3.. What could that be???

Upper leaf
Although the general condition of the plant looks good, some upper leaves started to claw. I would like to get expert opinion on the cause and solution of this.

Crumbly fresh leaves (week 2 flowering)
About those crumbling leaves: does anyone know what the reason(s) might be? As I've said: semi broke some branches, there's 2 fertilizer tablets in there, and I sprayed them with boomboom spray 3 times in total over the last 4 weeks.

Brown rust spots on oldest leaves
Brown rust spots on oldest biggest leaves with curling inward - the rest of the flower is fine, just some occasional small yellow spots. No sign of pests. Maintaining pH ~6.5 but have soft water. Suspect cal/mag deficiency or nitrogen toxicity. Thoughts?

Hey guys. Leaves not curling upwards as such but I'm getting some leaf tips that seem to be reaching upwards slightly. Does this mean I need to up her cal and mag intake? I read somewhere if the leaf tips are starting to "pray" towards the light it could be a cal/mag def?

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...

Asymmetrical baby seedling
Hi everyone, just need an opinion on my poor seedling that looks a bit mutated and stressed, came home today and my timer decided to break and just stay on no matter what you press.. My heater comes on when the lights off and was 28c in there 🙄 should I move the light away?

What’s causing my leafs to curl?
Leafs are curling inward on new growth. It’s not exclusive to the tops. It’s only 2/4 plants. It’s still growing fine as it’s my tallest and biggest plants. I’ve adjusted my light down to 2/10 as my first fix and moved the fans around. Any suggestions?

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!

How do you solve the problem of too high a box temperature? The first thing I will try is to put ice bottles in the box, do you have any advice?
