This grow is in beginning of sixth week. Was going good. Noticed slight yellowing (burn) tips leaves. I got carried away with fertilizer trying to bulk up flowers. Tested runoff, was very high, and ph got lower. ( PPM was 2200 and ph in one was 5.7.
Flushed with 3 gallons water each plant. Got PPM to 1300-1400. PH at 6.3
Should I give it one more flush or is the PPM at an exceptable level?
When next watering I’ll just give ph’d water try to get ppm down to about 1100. Am I on right track here?

I wouldn’t flush them again. I might not have even flushed them once. Yellow tips are just the very beginning of nute burn, nothing serious. The high ppm of your runoff is not necessarily too much added nutrients. Depending on what kind of soil you’re using it might just be organic materials breaking down like it’s supposed to. Your plants look good.
