Checked pots and it was time.
Adjusted PH on RRF and Super: Last adjustments for all three.
RRF - now - 6.53 (was 6.60)
Supersonic - now - 6.59 (was 6.80)
And last check CM was and is - 6.55
I wanted to make adjustments without a major flush because the numbers were not severe, however, the plants are really
sensitive. My technique over the last two adjustments has been as follows--with pots not bone dry:
Part 1
1. Run two quarts of distilled water slowly thru pot.
2. Dump any run-off.
3. Wait for all run-off to stop.
4. Run another quart through.
5. Dump run-off.
6. Collect next run-off and get a PH reading.
Part 2
1. Fill gallon jug with R/O water.
2. Adjust PH based on Part 1 run-off PH.
3. Follow same steps as above.
Part 3.
1. Prepare gallon of R/O water and very modest amount of feed and Great White (I know adjusting ph might neutralize the critters before they hit the soil--but--it's expensive and need to use

).
2. Adjust PH based on Part 2 run-off (usually small adjustment).
3. Run about 1/2 gallon thru.
My soil drains quickly. Consequently, the plants are not being subject to over watering/drowning. In heavier soil the above would not work and a flush would be better.
Now, I might be way off on this method. Seems to be working. Comments are welcome.
