NEED HELP; Blueberry Cheesecake; First Closet Grow

All,

This is my first time growing in a closet. I have two Blueberry Cheesecake feminized seedlings that have sprouted and are 5 days young. My set up is as follows:

-2 Double 22 inch Fluorescent 4,000k Bulbs
-Lights are suspended about 2.5 - 3 Inch above seedlings. Right now 18 hrs on, 6 hrs off.
-Soil is store bought, not Miracle Grow. Sterilized soil using oven @ 350 degree for 30 min.
-Water I use is boiled then left uncovered in a sterile plastic tub for 24 hours; then covered to prevent contamination.
-I soaked the soil before planting seeds. Now, only water when topsoil is dry to touch (Back of Hand)
-I also did not transplant, I started in a 3 gal bucket
-I have a Ozone Gen (Smell) in the closet but have not activated it yet as I feel this is too early and would damage the seedlings. Don’t plan on using until late vegetative stage.
-Small fan keeps air circulating in closet
-Temp is between 78F day and 72F night
-I open the door twice a day to bring in fresh air


I have not used any fert as of yet but do plan to once the seedlings reach 3 nodes. I then plan to fim and LST at the fourth node.
I have attached a few pictures of where the growth progress is.

Few questions after you look at the pics.

1) The stems are greenish brown; I have read a ton of threads, some say this is normal, some say this is a fungal disease. From the pics I've posted, can you please let me know the health of the seedlings?

2) The tips on the side of the fan leaves are curling up; From what I've read the Light Intensity is too high. Is this true?

3) The fert I plan on using is the Fox Farm Trio. Any good, "Real," reviews on this product?

4) I feel that they may have stretched a little but not to the extreme that I’ve seen online. Is what you see okay?

Pretty much I am inquiring about my process and about the condition of the plants thus far. Any help is greatly appreciated!

She looks fine. Biggest thing you need to do is chill or else you are going to kill her with love and worry.

Lights - you didn't specify what kind of bulbs they are or their wattage. Not important now but no way to know how much light you have for later

Soil - store bought doesn't say what it has in it so far as nutes are concerned. If nuted, don't add any nutes until she gets bigger and starts to become a lighter color

Water - don't waste your time boiling, covering, etc. Not necessary. But I would recommend PHing it to 6.5.

Pot - next time I would start in a solo cup and move into the final pot once established. Little plants in large pots are more difficult to water. They don't use much and peeps hav a tendency to overwater

Nutes - I like dynagro foliage pro, it is all you need

Haha chill, copy that.

Appreciate the words GDad. My lights are Double 22 inch Fluorescent T8 4,000k Bulbs. In regards to the soil I do not have the bags any more. It was a mixture of a potting soil and then a moss soil. The soil is light and bouncy. Ill check out the dynagro foliage pro. Then the water, the area I live in doesn’t have the best quality water, I hear you saying its not necessary however I feel safer continuing to boil. I will start to PHing it to 6.5.

Thank you again for taking the time to respond so thoroughly!
