Hey dude thanks for looking in on my grow journal and now i am here looking in on yours
Anyway as has been said already you need to get rid of the tin foil and use just plain white material of some kind or buy some mylar.
I would suggest buying a bag of perlite and mixing it with your soil when your ready to transplant at a ratio of 80% soil 20% perlite.
I never feed my plants anything for the first 4 weeks.
There should be enough nutes in the soil to last that long and it can shock or burn them easily if you use it to soon.
I also use tap water and i found a 1 part nute for hard water that brings the ph to the correct level for me just by adding the correct amount of nutes to the water.
I also bought a bottle of citric acid for when i don't want to feed them to lower the ph to the correct level.
If you use a water filter it will bring your ph to low so you will need to raise the ph instead of lowering it,i know this from my own previous mistakes.
I am about to buy a small unit that destroys smells for only 24.99 and only uses 5watts of power.
It uses ultra violet photocatalytic technology to destroy smells.
It is suitable to remove smells from a 15 square metre area and a lot cheaper than a carbon filter.
Heres a link for one but i don't know where you would find these in your country but if your interested you can use the info in your own local search engine.
I don't buy mine from here as i can get it at Argos for 24.99 but this page has more detailed info than Argos.

Anyway as to your plants everything looks fine so far.
If you can afford it i would suggest investing in a 250/400 watt switchable hps that you can use blue bulbs in for veg and red for flowering.
Use the new 7200k mh bulbs for the best results
