Leaf problem/ cracks

Hey, my plant has a problem whit leafs.
30 days old plant. Leafs are dry and feels easy to brake in middle. Leafs have like holes, but it is more like it has broken and deformed holes or cracks. The cracks tends to be on leafs edges and be up to 0.5 cm long/deep in leave.

Temperature is 25 degrees by ( Celsius )
Plant has kinda fresh air form outside.
I’m pulling in fresh, cold air from outside to col my HPS lamp. I don’t know what’s up with humidity, but from yesterday next to the plant has bowl of water. Hopefully it will keep up it.

I’m using tap water, it has 7 ph ( yesterday I tested whit ph indicator papers ) and the plant run off water had a little bit below 6 ph. Yesterday I planted in bigger bucket - 7,5 L ( almost 2 gallons ) Roots looked kinda fine, I was expecting more roots. For the first time ever I used perlite and for the first time plant was overwatered till it had run off water for ph test. I used to water every 4-5 days, mainly checked 2.5 cm of soil surface with finger to feel if it is dry. Every second watering added nutrients ( please check picture ) like 2 spoons ( added with fillings, without spoons )

this is my ninth plant, all the rest are dead in a year. I guess they died form heat, overwatering, really hard over nutrient dosage + cold and once i guess my seedling was to cold ( they did burst 0.5 cm long , but didn’t grow farther )

It seems like the you have a mechanical friction going on.
Do u have a fan blowing on them ? if you have make sure to make it slower or not pointing directly to them.
also check under the leaves, if you see any spots, some bugs or mites.
also u have to check the humidity.

maybe you can work better on your humidity and air circulation and heat management in order not to lose time and plants and money.

try not to over feed or water specially when its hot in the grow room as this might develop some root issues quickly, always less nutes and water is better.

Thank you for taking your time to answer.
Yes I have a fan, but mainly it is blowing air on HPS lamp. Plant was getting air flow on it too, but it was small air blow. Now I moved the fan that it isn’t blowing air on leafs. I every day take my time to check under the leaves, but with naked eyes. I haven’t see anything suspicious, except that cracks/holes. I will try to get some magnifier glass to check closer and I will get device to check humidity in grow room.

Today plant leafs felt less dry to my fingers. Two days ago I placed fly paper trap. I have catch 2 small flys. I read that flays can also mess with leaves, it’s true ?!

My temperature is on point 25 degrees.
I will resolve problem whit humidity, but I don’t know, know much plant needs fresh new air.
Next time I will water my plant and feed it too, when it will get like really dry, because
previously I over watered it. And I will give it like one spoon of nutrients.

You most welcome.

well they need co2 but not fresh air. I have had many grows without any fresh air, just watch for humidity and temps, actually u can buy a small humidifier for cheap.
