It would also be helpful if you could write out in a lot of detail the process of adding these amendments to the water. for example:

Supplement schedule:

Monday 9am added 100kg Urea
Tuesday 3pm added 20kg iron sulfate
Tuesday 6pm added added 4L 30% phosphoric acid and 4L 50% sulfuric acid
…

Irrigation schedules are Mon, Wed Fri. 10am

…

Sap samples are taken Monday 9am

The order and timing of supplements, irrigation and sap samples, are important, based on the types of changes you’re making.

With the supplements you listed, your water chemistry in changing significantly in 12-24 hours.
