To me it looks like damage caused by the leaves hitting either the side of the pot or the soil surface, most probably at night when the leaves are lowered and when the fan blows on them, causing them to rub and then leading to the damage you see here.
Without many more detail, this is my best suggestion that I can interpret from one picture.
This is not an issue caused by temps and 25 is not hot, 45 deg C is!
Hope this helps, Organoman.

Would check run off ph first. If out of line correct. If in range then extra magnesium and potassium would get you on track.

When to stop misting seedling? What to look out for before watering normally?When can seedling root system handle normal watering, NOT misting to absorb moisture through leaves? I want to avoid overwatering. Outdoor grow. I've misted for the first few days, started watering using a turkey baster yesterday + today w. 6.3PH at topsoil and bottom dish.

Why do my plants only have that light greenish yellowish look at the top and why is one of my plants also having those sick leaves at the bottom?2 of my 3 plants are a bit yellow-ish at the top since about a week. Plant 1 also had a couple of sick leaves at the bottom that I did remove. Those leaves had brown/dark spots, felt dry like paper, had very purple stems and did smell more like hay. More info in my report.

Is this a sign of a hermaphrodite?I'm afraid one of my plants might be hermaphrodite.
Today i spotted something that looks like male pistils.
I removed them carefully and found something similar at the plant and removed it aswell.
Should i remove the plant from my tent (3 other plants are inside) or keep it?

Foxtail Ready For HarvestHello. This plant of mine became foxtail. As the harvest time nears its end, blooms have begun to bloom again on their hills. Now the first flowers at the bottom are ready for harvest. What should I do? Should I harvest immediately or wait for the new flowers to mature?

Week 2: One of the plants still doesn't look good + other beginner questions :)Second week and one of the plants has weird spots + leaves curled.
Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea.
Also, when should I start feeding the plants?
And how much water do I need at this point? 😥

Is that not enough calcium?How can I recognise that it is only a calcium deficide? The plant is also the largest and the only one with such deficiencies. Could the plant also be lacking manganese or magnesium and what can I use to compensate for this? Are pests or diseases excluded?

18 weeks, but I'm not sure she's ready.The plant is 18wks old. Leaves are getting yellow, some buds are so fat the branches bend under the weight.
I'm worried some pistons are still white and I can still see some clear trichoms, but she's 3 weeks after the recommended date of harvesting.
Do you think she's ready?

Healthy?Sie wachsen zur Zeit sehr schnell allerdings haben manche Blätter Flecken wie man sehen kann. Die ersten Wochen habe ich leider mit einem zu hohen Ph Wert gegossen (ca 8) dies habe ich jetzt aber angepasst und sie bekommen ihre 6,4.Vielleicht Nährstoffmangel? Bio Grow hinzufügen?

Why dont my plants grow towards the middle/light and instead concentrate near the walls?Looks like my plants are growing towards the wall and not towards the middle where the light should be the best.
Why do the plants behave like that and what should I do?
Raise the net, rotate some of the plants, then redo the net?
Remove the net completely?
leave it as it is?

What do you guys think?It's my first grow (automatic, 6 weeks old) and compared to other plants, my plant looks a bit small/ridiculous. I give her 24/7 light (I read that on guides) is that maybe too much? What's your impression of her? I use two growlights (one from above and one from the side).
