So is it some pest problem?

Well.. it can be. The method I provided will help cover your bases with a mild solution. Reality is seeds can have bad genetics. Bugs cause fungus. And other disease. It's hard to say. If you see little bugs. Or evidence of. Yeah they are the issue. Diatomaceous earth cuts em up and dries them out. And it's harmless to you and plants. Layer on the soil is like a floor of shards of glass. So in short. I offer a generic cure all.

The reason I ask these things is because if you had put it in direct sun when before then it was only receiving natural light from indoors the direct sun would have shocked it. Too much too quick.
You said the leaves dropped u til you put it back in the shade I suspect your plant did not come away from that injury free. That blemishes on your leaves look like just as you suspected. Heat stress or sun damage from not hardening it off slowly enough to the direct sun. Nothing looks that bad to me other than needing to get some serious photosynthesis going on. Unless I missed something??
So baby steps to get it out into direct sun. This same thing happens to veggie and flower seedlings as well.

The silvery spots on the leaves? Thrips can leave damage that is just that, silvery spots on upper side of leaves. Generally they won’t follow the margins though it will just be random. You would find them on the underside of the leaf. They are soooo tiny. You can look and look and never see them, or you can look and see a tiny speck generally long and skinny. What I do it get a matchstick or the like and poke at it and watch very closely to see if it moves on its own. Then you know it’s not dust or other debris it’s ALIVE! In which case the advice you received earlier would be in order. If your worried about pm ( powdery mildew) you can mix 1 part milk to 10 parts water and I shit you not it will eradicate it and your plant will benefit from the milk. You can in a couple days spray the leaves down w water if your afraid of sour milk smell but at that dilution I have never experienced that. Good luck keep us posted.
oh yeah you may want to hold off on removing any leaves quite yet since your plant is still small. Only take them if they look like they are doomed anyways. A few blemishes won’t hurt anything. Once it gets into full sun it will explode with healthy vigorous growth. At this point loosing a few leaves is okay. The damage to your baby is so slight that some may not even mention it so no need to be too anxious about anything. Looks like you’ve done an excellent job raising it thus far on just natural light. Not an easy thing to do. 👍

Thank you very very much for the time you spent to help a totally new grower.I cannot tell you how much I appreciate it. Your words made me feel better and more calm!About the mik now.Somewhere I saw that the milk is bad because it binds the oxygen in the soil.But I think I will follow your advice!

I was reading almost everywhere that you plants need as much light as possible, so i thought that I was doing the right thing.Also I took them in the shadow when the temperature was more than 30 degrees celcious to avoid the heat stress.But it seems that I did wrong. So much direct sun even with normal temperature, damaged my plant.Now I have it for 6 hours direct sunlight(3 morning hours, so the heat is not too strong and 3 hours before the sun goes down) and then I put them in a shady place. The sun doesn't hit it at all but I have it outside so the place is bright enough.Will be a fix to photosynthesis or a problem?

Sounds perfect! When you spray the milk mixture if it’s diluted ten times one and try to just hit the leaves and undersides. Don’t like give it a bath in it and it shouldn’t get into the soil enough to do any harm. The leaves will feed off some sugar or something I can’t remember what I waytold. Anyways sounds like your in good shape!!

My concern is the sun because even if I'm living in a country with plenty of it and Mediterranean climate, the summer is quite hot with temperatures about 35-36 degrees.I think I will have to face the heat stress all the time.😔 I don't know how the plants can grow in those situations(I mean direct, hot sunlight) and always wonder how the plantations survive.Anyway,maybe when it will grow more,I will expose it about a few hours more. As you said, baby steps! Thanks again and God bless you my friend.

You need to transition it slowly. Start by putting it out in the sun where is hot but the sun is indirect. Do you want to get it used to the heat as much as you do the direct sunlight. So heat and indirect sun for a half an hour and then the next time a little longer and a little longer. Unless you’re going along your movie get into sunlight that is more direct at the same time. If you did this for two weeks with a slow transition you could harden any plant off to the sun and heat. Any heat lover that is and cannabis fits that category

I’m sorry I was voice texting and not proofreading. Move your plant to a spot that is sunny but indirect. A bit sheltered like under a tree where the sun gets filtered through the branches but your plant gets a dose of hot air as well as some sun rays. Try 30 minutes if no stress is evident bring it back to shelter and try 45 minutes the next day. Keep doing this combination of heat and increasing sun rays (moving it closer to the edge of the tree canopy). When you can put it in full direct sun at that first time only leave for 15 minutes. Then keep increasing. If u see stress (droopy leaves) it’s totally cool it just means you need to slow it down. The plant will tell you how fast you can “harden it off”. If u end up w a bit more sun damage no big deal. I hope this helps and I am not being monotonous lol

you are extremely welcome in every sense of the word lol. I’ve been helped lots over the years so trying to give back anything that may help feels good. The hard part is trying not to come across like a “know it all” because I don’t. You know how it goes, the longer you do something the less you know? Anyways please keep us updated I am hugely curious how the hardening off process will go in a climate such as yours.
Do other folks grow outdoor cannabis this time of year in your location? I am assuming yes otherwise you would not be trying. So if they can you DEFINITELY can👍

Yes definitely! I’m so sorry I didn’t see your post and rambled on and on. If you are to that point with no stress evident to your plant and it’s drinking water you BET! It’s going to start to bulk up. As it does you will be in full sun all day before you know it. Great work!! Kinda just ignore my last two posts. Again sry for missing this lol!

Sry I’m a bit scatter brained right now. Crazy day. Pm me if you want me to be more clear or specific in some way. I should have read your post closer before spouting off so much. Ttys

don’t dilute the milk, maybe a bit of water to help it through the sprayer. use it on hot sunny days as it needs intense light to have affect,
i agree it works great and also it’s healthy for the plants and helps boost their immune system, outdoors i spray the with milk just for the sake of it..
in some countries where it has hot sunny weather they use it on all their crops..

does it wipe off if you wet your finger and wipe it?

Yes I forgot to say spray in light but not diluted? on just a small seedling for what might be a tiny amount of pm? I was thinking prevention rather than treatment is all. I thought low dilution was a method for serious infection is all. I was afraid of her poor seedling drowning in sour milk is all. Not AT ALL to disagree w you. To the contrary Much respect 👍. 😁 I’m learning every day ✊
