suggestions and some leafes problems

Ok, boys and girls this is my closet grow, i need some suggestions, of any kind ... what would u thinkthat would make these plants more "vicios" .
In the first picture u will see that the leafes are a lil bent on the sides ... i don`t know why, is that good or bad? What should i do?
Tell me if im keeping the light at the proper distance ... the average temp is at about 25 degrees celcius maybe 28-30. I water them every 2 days with 200 ml. The humidity is ... at around 30% but when i am at home i water the closet and the leafes with a pulverisor ... I don`t use any fert yet ...
Tell me what u think i should do ... maybe they`ll get better and bigger.
almost forgot, i`m growing Cindy`99 XStrain (i don`t know what`s the diff but i just felt like telling you).
Thanks guys.

The leafs that are bending up on the sides show signs of heat stress, ur RH prob (30% is way to low for veg cycle) helps on this to..my sugestion get some ventilation in there asap..btw if that is foil that u have on the growbox, get rid of it foil creates hotspots that can easily damage ur plants, use either white paint or mylar as reflective materials...i hope this helps

"Fox farm grow big" what is this? Where can i order it from
How can i make a more humid grow closet? I already have a few pots with open lids so the water evaporates. Give me some more ideas! Please

Cannabis seems to respond best through a range of 40 to 80 percent relative humidity. Loosely enclose the garden with aluminum foil, white sheet plastic, or other materials. This will trap some of the transpired moisture and raise the humidity in the garden. Once the seedlings are growing well, the drier household atmosphere is preferred.

A lower humidity (50 to 70 percent) produced slightly more potent plants than a higher relative humidity (80 percent and over).

If you want to add more humidty add a bucket filled half way with water.

ur pots seem a lil big for the lil size of the plants u might have put them in pots half that size first. sometimes u get dry and wet pockest in the soils which can cause some serious root issues. but ur humidity is way too low try for 50 - 60 %
