Nutrient lockout acidic soil

So I think I’m experiencing a nutrient lockout due to my soil being to acidic and possible salt build up. I’m noticing a really bad magnesium and phosphorus deficiency/lockout and it’s starting to spread to a lot of my leaves. My plants are well fed so they shouldn’t be lacking any nutrients.

I’ve been feeding at ph levels of 6.3-6.5. Ppm 1100-1300 On week 5 of flower I tested my runoff water and it read a ph of 6.0. I water feed water. If I watered at 7.0 ph and skip a feeding or two would that bring my soil PH back to the normal range?

You won't be able to raise your soil ph by raising water ph. That would take years! The soil will out buffer that water. You can top dress with some ash or lime, but it will be slow going to get the ph up.

sam1510, you need to put up more info and pics, like what soil are you using, what fert, how often do you feed them, etc., if you want help.
