Help with ph issue

[CamoCannabis]

I have a well and use it for all of my indoor and outdoor growing. I noticed some yellowing in my clones and a couple of my plants in flower. You can see from the pic that most of the plants are doing well, but some aren't. I tested the ph yesterday (AFTER watering) and found it to be 7.6. I used ph down and got my water buckets down around 6.0.
Indoor won't be an issue for adjusting ph, but my outdoor plants will be a huge PIA, if I have to adjust it in buckets for watering. So, my question is.......what can I do to help with the ph issue for the outdoor plants? Should I add dolomite to the soil before planting them outdoors? I already have premium soil in the pots, but stressing on the ph issues. Also, since I watered yesterday, should I go ahead and flush them today or just wait a couple of days and water as usual?

Any help would be appreciated.

If you're lowering pH, don't use dolomite. Good luck. -granger

I would use dolomite outside but thats me. I used it indoors before and never used to ph in soil. Anyway to use rainwater outside? Might be more acidic if you can get a rain barrel....

That being said I am currently in hydro have been for years and only use reverse osmosis water from my own filter and always ph.
