New Grower Help with feeding, mid to late flowering (PPM interpretation)

[Bayes]

Hi-

First time grower here...

I have a Hanna Combo meter (50%conversion factor). Last feeding's runoff measured 1010ppm and 935ppm. My understanding based on forum reading only, is that these readings are fine but on the high side which I suppose is a good thing (little or no leaf tip burn). Ph was fine.

I'm a Fox Farm grower, soil and nutes (Trio).

I'll settle for a wild ass guess as there must be a ton of variables. My general question is for a plant in mid to late flower, how much does the plant consume as measured in ppm between feedings? Are there any rules of thumb??

I really don't want to do a rinse to find out what the ppm is today.

I'm really very interested in GENERAL guidelines for feeding when the the previous ppm runoff is known and perhaps a bit on the higher end of acceptable range. More specifically, does a tsp of Tiger Bloom add the same number of ppm as say Grow Big, or for that matter, molasses?

Not related so much to this question, my plants are at Day 44 and my grow journal is here: https://www.autoflower.org/f5/journal-white-widow-ministry-cannabis-first-grow-31968.html

Thanks in advance for your responses.

Wish I could help as I'm using the same stuff. But I'm running such low concentrations (below or at 1/4 strength) that I'm not even bothering to track EC/ppm.

Running a small amount of Big Bloom and Equilibrium Ca/Mg every feed. Grow Big or Tiger Bloom every other feed. (stage dependent)

Good luck!

Thanks Trapper-

But the question remains in simplest terms:

How do you use the previous ppm results to adjust the next feeding? Or do you?

If you keep the same PPM for your next feeding as the one from the run off, the PPM will not change... as long as you are feeding only when needed.

THANK YOU! This is exactly what I wanted to know.
