7.5 pH sounds high, though I'm not familiar with the feed you are giving. What does the manufacturer suggest the pH to be?

7.5 is high indeed, here is a schedule of nutrient uptake at a certain PH level for our beloved plant.

A PH level between 6.5 and 7 is highly recommended.

Flush the plant with 6.5 pH water. If your pot is 5 gal then flush with min.of 5gal. If your pot is 10 gal flush with min on 10 gal., Etc.

I use biobizz organic ph- myself so i dont really know anythng about other organic uses but i did read about lemon juice before on here so that should work. There are probably plenty of threads about that so i would recommend looking in to it before using it.

Once you have that figured out flush you're medium like Garybo said altho when i flush my plants i use 3 times the size of the pot. So with a 5 galon pot i would use 15 galons of water. With the third time i would use at least 1/4 of the feeding dose you would usually give seeing there won't be much left after the third flush and by giving at least 1/4 there will be something for the plants to use. Once it dried out you can start giving you're normal dose again with the new corrected ph value.

So should i flush then normalize the ph in the water and add that water to the soil? Then give 1/4th nutes to Ph'd water? Im not too sure how that works.

You should should flush twice using pure water using PH6.5 and on the third flush you add 1/4 nutes.
Then let it dry up (not completly dry ofc) and then start with what you're used to feeding. After that it should all be ok :)

Also make sure you don't water to fast. Let the water sip down your soil slowly and keep about 20-30 minutes in between flushes.
So all in all it should take about 1,5 hours in total.

I did a flush and the ph is at a 7. That should be good right? Or still too high? I didnt add any nutes yet bc i didnt have time before sun came out so i will feed tonight.

How much water did you use to flush?
If it's at 7 now and you keep you're feedings at 6.5 from now on you should be good :)
After a week or so add water until you have about 15% runoff and you should see you're PH being under 7 for sure.

I didnt measure precisely but i had a big bucket I been catching rain water in and basically used the whole bucket and checked ph and watched it go down to a 7.
