I have no clue what this is

Hi. I'am a first time grower here. I am from a tropical country, so controlling my grow room environment is pretty challenging. Im currently on my 4th week of Veg, and my plant is showing some signs of deficiency- I am not sure. Although it is very minimal, I just wanna get on top of it as soon as possible.

Currently, they are growing in 1 Gallon fabric pots and I plan on transplanting them this weekend. I use GenHydro for nutes and I used to do daily fertigation, but I am not doing every other day. They actually seems okay, except that one of my plants started having white wilting spots. Maybe 5-6 small ones, in different leaves. I have been doing LST as well as Mainlining. My Light Cycle temp is between 26c-29c with Humidity between 55%-65%, at night, Temp is at 21c-23c with around 35%-40% RH.

I also think that the same plant having white spots (the spots doesnt look at all like any PM I have seen, they all look like browning but instead of brown, they are white, I cannot rub them off) are showing signs of mildew, but I am not sure. What do you guys think?

I'm not sure man, I would open up your own post for it to ensure the most people see it. I just finished my first grow so I am no expert and I highly suggest getting another opinion, but the curling leaves, little dots, and some vegatative growth missing almost looks like thrips to me.
