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.

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. ✌️

Hi everyone. I'm in the 5th week of flowering and have had slightly curled leaf edges for about 2 weeks, and the newer leaves look a bit dry. I haven't changed anything except for maybe a bit too much fertilizer. Could that be the reason? I appreciate any tips!

Small yellow spots
I have small yellow spots on leaves. I want to say it starts at tips and travels down. I moved light away and it seemingly gotten better. I moved tents for bigger space and it might have returned.

Surplus or deficiency?
Can't tell if there's a surplus of nutrients or a shortage of potassium? One plant looks like nitrogen burn and the other two look like theyre maybe a little k deficient. Was thinking of chilling out on the feed on the burnt one and just feeding micro to the other two. Thoughts?

Classic N toxicity (:
Heyho :) since she has progressing leaf tip burn and curled tips which I'd almost certainly say is a nitrogen toxicity, would you recommend going down to 50% general strength or maybe leave out the grow supplement at all and just feed Bloom? Cheers guys :)

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.

Leafes curl up
Hey, these are my Autos at the beginning of day 6. The leaves are curling up a bit, is that normal/okay? Or is it light stress? The lamp is an AC Infinity Evo 4 300 watt, I had it running at 40% since day 1 and then reduced it to 30% after day 3. The distance is 45cm.

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.

Dear experts, could you help me ascertain whether the 4th and 5th picture on my Week4 diary is really heat stress? The only reason I think that is because of that slight cupping/curling of the leaf edges. Might there be other problems that could cause this?
