名媛直播

Hi guys, first post here and first "tree" of my life
I bought pine bonsai seeds (5 seeds) in Japan, planted them indoor, growing them (only 3) successfully for some months (first seedling in October 2017). I have changed now the apartment and I don't have much direct sunlight so I got a lamp to make them grow (10W LED Plant Grow Light). After using the lamp, I noticed that some part of the trees are getting brownish (picture attached). Is it because I'm "burning" it or it is just the way they grow? I am watering them every morning with plenty of water until the soil becomes wet with spray water bottle. Usually, when I water them, the water is going on the trunk and on the leaves that are now brownish. Can be because the water is cold or because too much water? Indoor temperature is around 22-degree Celcius.

Considering the small pottery and the 3 "trees", should I repot them in separate potteries maybe using a special soil?

Thank you very much for your help!

Why are you calling these seedlings bonsai?
名媛直播 seed does not exist.
Pines do not belong indoors.

Congratulations on getting to this stage.

Especially as pines are really strict outdoor plants, it is a bit of a challenge to keep these alive indoors. Once winter is over, do move them outside.

Tat being said.. Nedles do drop. It can be the aging, in combination with being indoors. Possibly the tree is just getting very little light and is therefor now investing in getting taller.

So far, these seedlings look quite healthy.

Do take note of Auk's post.It will be a few decades before these will be in a stage that the badge "bonsai" is suitable.

Looking at the 3rd photo I'm going to guess that's not going to happen.

Thank you Auk for the clarification

Thank you leatherback for your reply!
Unfortunately, I live in Dubai (UAE) and I believe I cannot leave the plant outside during the summer, it's almost 50 degrees Celcius!
The tree is now getting a couple of hours direct sunlight in the evening and it is not growing as before when he was with direct sunlight the whole morning. This is the reason why I decided to buy the lamp. So if the brownish needles are not because of the lamp, I would keep using it during the day, what do you think?
Would you recommend me repotting them in three separate potteries or they are still small?
Last question about watering: I read that it is better to water them without the spray bottle because the water needs to run out of the drainage holes so the entire root system is wetted. Would you agree?
Thanks again for your help!

Hm.. If you cannot move them outside, you are setting yourself up for failure I am afraid. I do not think I have ever come across anybody growing these indoors for any serious amount of time.

Pines need loads of light, so yeah. leave the lamps.

I see. So I'll try to do my best then and let's see how long I can manage to keep him alive! I'll keep you posted!
Can you suggest me a plant I can grow inside from the seed which might become a bonsai in two decades?

Dubai "Winters are warm and short with an average high of 23 °C (73 °F) and overnight lows of 14 °C (57 °F)"?

So... no cold period for your pine. Seems not likely it will last longer than a year.
I cannot suggest any plant for bonsai to grow inside from seed.

If your plants were burning and the lamp is above them, then the burning would happen at the top of the plants, which is not the case, could you be over watering the plants? Also there is no such thing as bonsai seeds.
