Poor Man Cheap Setup First Ever Grow!

My first ever grow. I'm growing in a modified fabric clothing wardrobe. I'm using one 65w and one 80w quantum board LED (LM281B). I think ive make a mistake buying china stuff from online rather than just adding few more money and buy a proper brand. Anyways lets see how it goes. I bought the cheapest seed I can find in Seedcity and I chose this strain from seedstoker because its the cheapest seed I can find. ( Cannabis is super illegal in my country and I did this (choosing cheap seed) just to test the water to see whether seeds can pass my country custom. Surely will buy more new and advance strain next time.) I'm totally new to this growing and I have none friend who grow too that I can refer. Ive been smoking brick cannabis for 15 years and I've decided I should try to grow and smoke the real thing because weed is the thing I smoke everyday. so I hope by putting it here open to the grower community you guys can point out my mistake or any concern throughout the growing process so that I can finally smoke a proper well cultivated cannabis from known strain. Don't be shy to comment okay. ***day 1 (10/11) - Planting seed directly in the soil mix...light water than cover it with plastic cup. ***day 2 (11/11) - Nothing happen. Spray more water lightly on the planted seed. ***day 3 (12/11) - In the morning, was curious and anxious so i scratch some of the top soil in order to find the seed. I just scratch very gently one time and i can directly see the seed looking white-ish. pretty sure its germinated so was relive. at late evening, seed start to sprouting. been covering it because humidity in my tent are still low. I've decided to run the light 24 hour and start the 18/6 cycle the next day. A lot of effort and observation are being done thru the night to increase humidity but I can only raise it to 70% max after spraying inside, putting water container , putting older plant inside but it will still dropping. ***day 4 (13/11) - (10am)wake up in the morning and my bigbud is looking like in the picture (ref 1). Humidity is still low at 50%. Temperature are okay. Been spraying ph balance water mistily in the tent and around the plant. I've decided to buy a humidifier today and lets see what happen later. ***day 7 (16/11) - still struggling with low humidity. waiting for ordered humidifier to reach me..temperature is always between 27-30'c. today i mix 3 litre of ph balance water with 30ml of growth nutes and water 200ml into pot.
