Well yes and no... I think it's more of an alkalinity issue. With low alkalinity you have very little buffering and the ph will swing quickly. I think you should add some buffering to the solution.I got the replacement Ph probe today and what a difference! The new one will get to target very fast and is very accurate. The previous one could be an amazon knockoff or it broke after a year. A working one should be very responsive and take less than 10seconds to get to target.
I checked the runoff of the rockwool and I am seeing ph of 7.1(that's with 1.7ec 5.5 going in). If that's what the rootzone is seeing, then couple elements are not able to be absorbed such as P
based on what you said earlier, don't let it go above .3 ph in 24 hours and 1.2EC. I will feed 1.2EC 5.8 and hope to see 6.1 runoff the next day. If the runoff ph is higher than 6.1, then run more solution through rockwool. Is this the way to go?
Yeah thats better than both Gh and ANI see what you're saying. I was under the impression there would be some type of buffering within the dry nutrient powder. What would you recommend?
I used advanced nutrient ph down before, it is much stronger than the General hydroponics one.

But I am now using this one from my local hydro store. It is much stronger than the advance nutrient one.
