Absolutely, here we go:

$14 Ph Calibration solution
$6 Spray Bottles (Did not use these much, only very early during transplanting.)
$7 for 30ctStarter grow bags$18 Hygrometer for Temp/Humidity
$8 for 6ct 5 gal Smart Pot knockoff
$40 - Soil: Two bags of Happy Frog. Ocean forest was sitting around.
Nutrients: $165
$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.
Good PSA
Here are some Links
Oakton PH2
Calibration Solution
Storage Solution
Get a good quality tester and keep it cleaned/calibrated and you will have it for a VERY long time :D
PS. I started out with a $20 PH pen and found out after some PH issues started up that it needed to be calibrated pretty much between each use. If I left it alone for a week it would be off by .3-.5 every time...
I mean it depends what you really need it for. Are you checking that your mash pH is +/- 0.1? I feel like unless we are fine using a calibrated $20 meter. I use this
Recently got a pH meter. It came with some powder to create calibration solutions, which I plan to do this weekend. I've read a lot that I should keep the probe wet in between uses. Do you guys use water or the buffer solution? When I was looking at buying additional calibration solution I found this set that includes a storage solution of potassium chloride. Is that necessary? Any pH meter advice is welcome! Thanks!

There's a cheaper one than this
Would that work?
Yes you can fix it but you'll need to get a few things. You need a cheap ph meter, calibration solution, and ph up/down. About $40 for all of it but controlling ph is one of the most important aspects of growing cannabis so you need this stuff in your garden.

Sorry, I don't know how to do the fancy links.
So i guess rinsing and washing it is good enough, thanks,
Here is where I got the formalin from:

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.
Get a calibration kit and calibrate before and after every measurement.
cheap ph tester
calibration packs for the ph tester
ph up and ph down (also comes with chemical test, but I’d get the pen)
Bok choi has been the easiest thing for me to grow by far so there's definitely something off in your system.
Having a pH pen and an EC pen is pretty much critical to diagnosing nutrient solution problems. This is the pH meter I have, which is kind of mid-tier but comes with calibration solution. Also pick up some storage solution as it will reduce how often you have to recalibrate the pen vs keeping it dry. EC meter you can go cheap on, I use this one and get good results.
No. It's an instrument. It needs to be tuned. https://www.amazon.com/15-Pack-Buffer-Solution-Accurate-Calibration/dp/B075L6TF1V/ref=mp_s_a_1_2?ie=UTF8&qid=1550100627&sr=8-2-spons&pi=AC_SX236_SY340_FMwebp_QL65&keywords=ph+calibration+packets&psc=1
I wanted a scientific grade instrument and found this pen for under 50 bucks and have been using it well over a year now; the only time it lost calibration was when the batteries needed changing. It gives quick readouts and comes with a two point calibration solution system along with a sturdy case with cutouts to hold everything. This is the storage solution I use to maintain the probe.
I didn't realize you'd already ordered the items in your list. That pH pen should work OK, but you'll need to calibrate it every couple of weeks. THIS kit has 4.0 and 7.0 calibration solutions and the storage solution. You definitely need those items to keep the pH pen operational (same goes for ANY pH meter). And you still need a tds/ppm meter... THIS cheap one should do.
Here is the mobile version of your link
If I needed such a thing, I would probably just call Taylor, and ask what they would recommend to test those ranges with. 1-800-test-kit. They are awesome on the phone.
I checked for pH standards, and Taylor offers them from like 2.0 and up, but most have dyes. They said they can make a version without dye in the pH of your choice, but that sounded expensive to me.
I found this on amazon, just searching for pH standard:
Clear 7.00 pH Standard Buffer Solution, 1L -
https://www.amazon.com/dp/B0731XBQZQ/ref=cm_sw_r_cp_api_i_LcFZDb1VFK51M
So if you mix precisely half and half with this, and get a true 8, the pH is really a 9.0. This may affect the accuracy of the ad test, so that would be another question for Taylor.
Most of my reaction to this question would be to avoid it altogether. I avoid doing curations of other people’s plaster like the plague. If you want to do it, you just need to be there the day it’s filled, and toss in 3x gal Ma. Come back tomorrow, test, adjust & brush, etc. NPC has an excellent class if you get the chance to attend one. Basically, it’s all about 7.2 pH or so, and >0 Chl until it stops dusting heavily, and balance it proper at 30 days, but I’d leave the calcium soft (200) until 60.

Really most storage solutions would be fine but this one is manufacturer specific.
You have to convert the proteins to polymer bonds, soak in this stuff first: https://www.amazon.com/TissuePro-NFB03-32R-Neutral-Buffered-Formalin/dp/B018REELP0/ref=sr_1_1?keywords=formalin&qid=1567485850&s=gateway&sr=8-1
then 70% isopropyl, the 98% can damage tissue.

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.
https://www.amazon.com/General-Hydroponics-4-01-Calibration-Solution/dp/B017H73794
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
Na. It comes with some calibration buffer. Calibrate it when you get it and it's golden. I've since bought some 3 stage buffer to make sure ph is accurate. The three stage buffer came with some storage solution but I don't use it. Just clean the testing end off after each use and it's fine.
edit: Here's the buffer solution if there's any interest.
I use [this] (https://www.amazon.com/Innovating-Science-Buffer-Calibration-Kit/dp/B00BUV7L96/ref=sr_1_4?ie=UTF8&qid=1472825418&sr=8-4&keywords=ph+calibration+solution) one. Like u/Boss_McAwesome said, you need more than one pH solution to properly calibrate.
They work great, and I'd really suggest getting one for hydroponic grows. I use an HM Digital pH-200 which is nice because it comes with a replaceable electrode, so when it wears out or breaks don't have to replace the entire meter. You also will need some pH 7.0 calibration/electrode storage solution as the meter will drift, so calibrate weekly. This meter is on the expensive side of pH meters for hydroponics, but I believe in the "buy it right, buy it once" mantra. Sure you can buy a meter for $40 but you'll end up buying it twice after the first one breaks/malfunctions/whatever, so just get the nicer one and be done with it.
