Correcting pH can lead to overfertilization?

Is it possible for nutrients that have been locked out due to incorrect pH to lay dormant in the soil, then be re-absorbed by the roots later on when the pH has stabilized?

I'm asking because I appear to have an overfertilization problem, and I stopped using nutrients a little while ago but only just started correcting the pH of my soil to 6.5. I'm thinking if all the old nutrients weren't being absorbed, they might have just been hanging out there- now that my roots can absorb nutrients, there are too much and my plants are being burned.

Is this possible? Thanks

I'm really not sure, a chelating agent would make a difference but I dunno if you're using one.

If the overfert problem continues flush out your medium with about 3x the volume of your planter (IE. One gallon planter = 3 gallons of PH adjusted water).

I have since flushed my plants, concluding that it could not harm them and only benefit them.

The apparant defficiency I had previously seems to be gone- I assume this is a result of adjusting my pH correctly. The ugly ugly nutrient burn has stopped spreading (after the flush), but the damage is fairly widespread.

I guess the lesson learned is that if your pH is off, do not slowly adjust it through multiple waterings- flush that shit out with tons and tons of pH'd water.

I don't think the nutrients get stored up as you say but the flush is still good. What you were seeing was probably the plant shutting down and not getting enough nutrient in reaction to the pH problem.

It is possible for harmful nutrient salt deposits to build up in soil if you are over feeding them or if your ph is off and you only lightly water. As you said above and already did, a soil flush is all that is needed(besides proper ph). I know it is listed as only use when needed, But any time my plants are showing deficiencies or burns, I flush, Let it dry out, and feed with properly ph slightly diluted nutrients. But this is all off of memory now that I'm a hydro farmer.
