Re: Queen's Sophmore Grow F - Lemon Skunk - Big Bang - Along With Some Bag Seed Sprou

Then I got to wondering how long should I do this or will once be enough?
You likely have "hard" water. Do you find scale builds up in your sinks and bathtub rather quickly? This is just a sign of high mineral content in your water. It also causes the pH level to be alkaline. I have that problem myself and have just ignored it.
If your pH is alkaline, you are going to run into pH problems unless you use an additive to your soil. I posted some soil supplements that can lower pH in the long term.
I'm mentioned I used lemon juice for the first time (results are great!).
What growers who have "hard" water do is one of the following:
1) Use lemon juice, vinegar, etc. to lower the pH; or
2) Add Epson salts to their water.
The pH of lemon juice is about 3, so 1 tsp / gal is sufficient.
The pH of Epsom salts is about 6, so 1 tbsp / gal is needed.
Of course, you know Epsom salts is also used to treat a magnesium deficiency.
Since my sensei,
Senor Marijuana, told me I should correct my soil's pH, I am going to use 1 tsp of lemon juice per gallon
every time I water from now on.
This is from the plant abuse chart at the end of the treatment for Magnesium deficiency:
If your starting water is above 200 ppm, that is pretty hard water, that will lock out mg with all of the calcium in the water. Add a 1/4 teaspoon per gallon of epsom salts to all your water.
Since the pH of Epsom Salts is about only about 6 (whereas the pH of lemon juide is about 3), I would have thought that 1 tbsp per gal would be required for each watering.
Regardless, unless you have a soil additive that will control your pH, you need to treat your water
every time you use it.
Since Epsom Salts contain mineral salts (well, duh!), repeated use may cause mineral salt buildup and eventually lead to mineral lockout, I intend to use lemon juice instead. Lemon juice has citric acid and shouldn't cause mineral lockout in the long term.
You can use 5% household vinegar (acetic acid) instead of lemon juice if you prefer. It has about the same pH as lemon juice (about 3), so you would use the same amount as you would of lemon juice.
I know this is long-winded, so let me summarize:
You want the water you use to have a pH of about 6.5. The water you are currently using probably has a pH between 8 and 8.5. So before you use it, add something acidic (lemon juice, vinegar, Epsom Salts) to bring the pH to an acceptable level - around 6.5.
So, that's it - adjust the pH in
all your water
before you use it.
