Yellowing leaves nutrient lockout

A couple of weeks before they start to flower late-stage vegetative. They started yellowing so I've been adding more and more nutrients and nothing seems to be working but they are getting more yellow how do I deal with nutrient lockout should I stop feeding in general and just water them? I've heard not to flush it and just stop feeding them and then I've seen too flush it. Doesn't nutrient lockout happen because of pH and salt build up. Should I flush with Epsom salt or just regular water. They also have a little bit of tip burn

Haveyou done a slurry test on your soil to acess the soils ph? Those leaves wont go green again, there yellow . What you need is more nitrogen in the plant food your useing. What are you useing ? Whats the NPK onthe packet/ bottle

I'm using foxfarm Trio the solution pushes over 1500 PPM ( I don't understand how the PPM get so high so fast after the ph up) but I do what the bottle says maybe a little under I usually get the pH around 5.8. I put a pan under a couple of plans to measure the pH water that drains through the soil and then sitting at a comfortable 5.8 6.0 but the PPM is sitting at 150 to 200 PPM after it drains out of the soil. Just did that now it makes me a little confused I'm not sure how accurate those numbers are. I'm not sure if I'm doing the slurry soil test right.

Should I stop putting calmag in my fertilizer solution going into flowering?

I have a small amount of tip burn though I would think I may have done too much right?

Yes thats nute burn when the tips go like that.
to do a slurrytest, get a 1/3 cup of soil and make a slurry with clean water and then test the ph . This willgive you an indication of what the soil is doing.
do you water a few times with plain. Water in between feedings?

Should I just stop feeding or should I flush with a product like sledgehammer or just good ph water? If I stop feeding about how long do you think I should stop feeding them. Should I try to take out half the soil from worst plant from the roots and replace it in the same pot with new soil
