First sorry to hear about your job, I’m on the verge of loosing mine I think and I’m a covid screener… Government is running out of money =p so we all feel the pain.
I can appreciate living in a small rural area, that’s how I grew up, my suggestion would to be go to fox farms website and look at how the ocean forest is made ingredient wise. This will help you soil shop in your local community, basically you want the richest soil possible if your not going to go coco/perlite mix (I suggest this but you started in soil this round and are already in 1 gallons so be it)
Unfortunately the bad Chinese scammed you like everyone else who starts out and sold you a 185w light claiming 1000w =(
The light is junk to be blunt, if you can return it do.
You need to deal with the more honest Chinese for lights lol, I recommend kingbright lights but they take 3 weeks to ship since they come directly from China although spider farmer is a similar (not as good and not as cheap But still good) manufacturer that keeps stock in the US and can deliver much faster.
Do you have a tent? Generally you need a 2x2 space for one plant, 3x3 for two, 4x4 for four etc.
Choose a space and then choose a light as you will need one eventually.
Ignore the scale. Learning when to water cannabis takes experience. Start by lifting the pot full of dry soil, then lift it full of wet soaking soil, when you check your plant put your finger in the soil until the second knuckle if it’s dry dry then water, if you feel Mosture then wait.
Lift every day and you will learn the feel, that’s the best method ignore soil readers.
Ignore giving half of this or a quarter of that.
You need a PH meter and a tds meter, use your tds Meter and the feed chart that is recommended by that nutrients company.
I strongly suggest buying Jack’s nutrients part A along with sourcing (or ordering from Jack’s) calcium nitrate (read as part B) and magnesium sulfate (read as part C, also know as Epson salts with no scents added)
It’s a 3 step process and its cheap, dry nutrients from Jack’s or someone like Chemgro are soooooooo much cheaper than any bottle nutrient and they even produce amazing results that top growers use. LIKE ME lol.
The way to know if you need to feed nutrients, as over feeding is a common mistake beginner’s make, is to water your plant in its fabric pot and read the run off.
So PH your water going in and read the tds of it, then read the tds of it going out. Take that tds on the runoff subtract it off what’s coming in then finally relate it to your feed chart.
While Keeping in mind the ranges cannabis needs generally base on its stage of life.
