From the photo it don’t look like a big issue looks to be a burn from water or moisture sitting on leaf in the light

Strange fan leaf markings
So I have some markings on the fan leads that I’ve never come across before. See the pics ... could this be bugs? Feed? Or a heat issue? Or is it simply mother nature , and the fact that we all have imperfections somewhere along the line?

Leaf stems change color
Greetings, dear Growmies! Growing NL auto by Sensi On 2 of 3 plants the petiole (leaf stem) turned red on upper (facing the light) side. The bottom side is green. Is it a sign of any deficiency or disease? Couldn't find on the web.

Slow growth / malformed leaves
This is my second grow and 1st attempt at hydroponics. This is the 20th day and the symptom is very slow growth and the leaves are dark green as well as they're malformed. I am using tap water that has been filtered. I am using a total of 4TSP / 20ml of Nutrient 500ppm

Deformed first true leaves on seedling
My Harlequin x GG4 seedling has a weird set of first leaves. They are very small, narrow, look deformed and bend down. This plant is being watered the same as the other plant that looks healthy (also a diff strain, gorilla zkittlez).

Red Petioles
I've noticed that the petioles on many of the fan leaves have turned red. They're not showing any other signs of anything being wrong. Anyone have any info on this?

Should I reduce N further?
Hey everyone, it’s been 11 days now since I noticed a Nitrogen toxicity, and I adjusted feed to 650ppm and notes in ratios according to GHE feedchart (numbers in diary). Just wanted to ask if you all thought they still look like they need less Nitrogen? I could reduce calmag?

I gave an N boost to both plants but the one I haven't being using LST on is presenting an issue on the leaves, they are turning dark green on the inside, wondering if it's the true healthy color or is a sign of excess N. There are more photos in the journal Thank you

One leaf issue?
The only leaf in the entire tent looking a little mad. My instinct says leave it and see if any others pop up. Thoughts?

How many times could/should I defoliate these Cobras? The Last photo shows a before & after which took place on May 31st and since that time, she has regrown to the point prior to defoliating. Should I repeat another defoliation? Far too many branches are shaded, again!

How common are 8 Finger leaves?
Doing some LST and tucking on one of my Purple Punch Autos and found this crazy looking 8 finger leaf. After finding it I noticed a lot of the top and new leaves have 7+ fingers. Her sister( which is the same strain) is normal. Is this a common occurrence ?

Beginning of week 8. Deficiency? Nute lockout? Normal for this stage of its life?
Beginning of week 8 and her leaves are showing more spots and discoloration everyday. Is this normal for an Auto in the late stages of flower? Or do I need to feed more? Maybe a flush? This strain says she takes about 10 weeks start 2 finish.

Spot on leaf and white tips
Should I be worried about this spot? It is just one leaf, appeared today, and i've noticed some tips got white/yellow. The latter appeared before any feeding was done. I've only watered with tap water and Power Roots. Nothing else was added until today. Plant looks great otherwis

After the watering a couple of days ago, it seems like the plant isn't doing well; the substrate is very wet, maybe retaining too much moisture (coco, hummus, and vermiculite). I've taken it outside to get some air. I'm afraid the fermented hummus tea might cause mold x7.

Spider Mites 1 week before harvest
1 week before harvest I saw some white dots on some of the leaves which might be spider mites. It's not that spread out yet and only on a few small leaves, I have seen no webbing either. Do I harvest ASAP or will the plants endure a few more days without it affecting the buds?
