Help! One of my plants is looking a little sick/sad and i dont know why!

[Coastal Dharma]

Hello all! One of my plants is looking a little sad and i dont know why.. Its gotten the same treatment as the rest of my plants and they're all looking fine.

I have 10 plants in total. They're under two 1200W ViparSpectra dimmable LED's, 4 fans running on fairly low speeds(more than enough to keep air moving), temperature hovers from 20-25 degrees celsius(68-77F), and a RH of 40-50%.

Their being fed nutrients every second watering and I have them in two groups of 5 so i can break up the amount of work to water them.

Their Waters/Nutrients PH is always 6.5-7
PPM is always kept between 200-600PPM(600 being max occasionally)

I keep a detailed grow journal and am very new to growing cannabis as this is my first grow..

The symptoms of the sickley plant is kind of skinny wilty leaves with a strange shade of green on parts of the leaves.

Attached is some pictures of the sickley plant and another one of my healthy plants as an example for contrast. The photos with a thumbs up is the healthy plant and the photos with a thumbs down is the plant thats sickley. Im also posting a photo of my grow journal. Not that anyone will be able to read my writing lol

Any input is welcome! Again i'm new to growing so please be kind and constructive. No keyboard warriors please.

Thank you everyone!

Oh really? There’s so many different opinions on temperature all over the web. Generally it’s been 20-30. I keep them in pro-mix HP. Thanks! I’m really enjoying learning about growing! It’s been an awesome experience! Thanks for the reply btw!

Oh and they’re about 40-50 days old. I’m doing a low stress training technique that keeps them very low and grows them in a spiral! The stocks are starting to look REALLY COOL! It will lower my yields but I’m okay with that lol I’m really just growing because my dad is sick(I’m going to make tinctures for him) and I love plants

Yes , it all depends from the kind of strain u grow , basically 27C in a day , night no lower then 20 C , veg time u want 60% humidity in the day , 70% at night and in flower when u flick the lights u want 40% in the day and max 50% at night . That culture of bacteria u showed on the photo is for transplantation, stress relief, it help plant to use food u gave them . On 40-50 days they look small to me but it might be weak Led light and wrong nutrition if is coco medium . If u grow in soil all natural to use for medical reason that is why is slow grow.. and bending nonstop slow it down the grow.
Overall is great idea and technic . Keep up good work !!

Yeap! The stress and all organics is keeping them small. I've seen some videos/pages where people are almost ready to harvest autos at the 50-60 day mark haha but i think itll be really neat to see how these plants grow. Once the stems make almost a full circle around the pot then 90% of the training stops and they'll start to take off. As long as their healthy im happy. Cant figure out why that one is looking so sad though. All the others are very happy

checked out your media btw. Those are some happy colas you posted!!
