$13 - Scrog net: for something like 50-100ft of plastic garden fence from Home Depot. Using a lot of it for a garden.
$15 - Miscelaneous: Eyedroppers, duct tape, zip ties, and odds and ends: Call it $15.
So to total that all out we're looking just over 1000 that I spent, could have kept it under $950 if I had not purchased the small duct fan or dehumidifier. Also: Soil and nutrients for $205. Could work that down to under $150 by dropping a couple unnecessary yet desirable nutrients.
Sorry for the formatting! I'm going to do a big post write up and this is a great place to start at least. Thanks for the motivation.

lol.
Mine came with calibration solution mix like in this video. I would recommend weighing your water vs. using volume. 1 gram per mL.
They also sell solution.
Find the instructions for your pH meter and read them, there should be calibration instructions.

All you need. Mine has lasted 4 years with very little calibration needed. Test it using these 2 solutions at least before every grow.
It sounds like you may have a soil with lots of a buffering basicifer in it like lime or some other (bi)carbonate.
If you have a cheap pH meter then it could be reading off if not calibrated. You want to calibrate digital pH meters at two points.

you have to calibrate your electronic one almost every time with this stuff: https://www.amazon.com/General-Hydroponics-4-01-Calibration-Solution/dp/B017H73794
