NO NEED TO DO A FLUSH!!!! FIRST WHEN YOU TEST RUNOFF!!! MAKE SURE DAT WHAT YOU CATCH DA RUNOFF IN IS CLEAN!!!! DEN WHEN YOU FIRST GET 1-2% RUNOFF TEST DAT!!! DEN TEST DA LAST BIT OF RUNNOFF!!!! SAY DAT YOU DO 15-20% RUNNOFF TEST AT 16-20% POINT!!! DAT IS WHERE DA PH IS!!! DIS WILL CHANGE ALL DA TIME AS EVERYTHING FEEDS!!! I KNOW A GUY WHO NEVER CLEANS HIS TRAYS AND TEST PH AND RUNOFF!!! YOU THINK HIS READINGS ARE CORRECT!!!! HE THINKS HIS EC IS 14 AND PH IS 3.5!!! DAT IS VERY VERY FUNNY!!! OH HE POSTS GROWS ON DIS SITE!!! I WILL NOT SAY HIS OR HER NAME!!!!!

If you watering the next time lower your water to 5.8 ph and check your runoff. Dont overwater your plant now! Stay cool your a little high in runoff but the plants look okay for now.

Hey there. I'm going to try to help you as best as I can. Don't panic, you haven't broken anything, but you need to understand the nuance between the pH of what you're giving and the pH of the soil. Here’s my analysis for your specific case: Yes, that's very good. For a soil grow (Living Soil or classic potting mix), the ideal range is between 6.2 and 6.5. During the flowering phase, we often aim for the lower end of this range (around 6.2 - 6.5) because that's where phosphorus (P) and potassium (K) are best absorbed by the plant. Going down to 6.0 - 6.2 with your nutrients is therefore perfectly correct and safe. 2. Should you "flush" with a lower pH? Definitely not. Flushing with a very low pH (like 5.5) to try to bring down the average of the soil is often a mistake that creates root shock and blocks other nutrients. If your starting water was at 6.9 and you're now watering at 6.2, the soil will naturally act as a buffer and stabilize somewhere in the middle. Soil has a great inertia: it doesn't change pH instantly. It's the consistency of your next waterings at 6.2 - 6.5 that will gently correct the course. 3. What to monitor (The "Runoff") If you have serious doubts about whether your soil has become too alkaline (pH too high), do this simple test: Water with your usual mix at 6.2. Collect a bit of water that comes out from the bottom of the pot (the drain/runoff). Measure the pH of this water. If the runoff is between 6.2 and 6.8: You're perfectly in the comfort zone. If the runoff exceeds 7.0: Just continue watering at 6.2 next time, the correction will happen on its own. My advice In your photo, we see plants at different stages (some already flowering, others very young). Be careful: the young plants at the top of the image have different needs than those flowering in the middle. Keep the pH at 6.3 for the little ones (growth). Keep the pH at 6.2 for those that are flowering. I hope I was able to help you. Have a great Sunday and good luck!
