Run off ppm 4500

Your pen needs to be replaced or recalibrated. As mentioned above man, your plants would be suffering hugely if your pen was right. Recalibrate or toss it on the trash and get you a bluelab pen. 👊🏼 muscle

Definitely an example of why this sort of testing is as much art as science and you need a good baseline before the data is useful to anyone. In this case you'dknow the value is astronomical relative to plant h ealth and ignore or re-do the measurement. The timing matters. early in runoff will be higher than late in runoff. if you have a lot of ongoing recurring issues or doing something new, it's not a bad habit to have. if you run smooth grows, spot checking is enough. I do soiless and religious about 10% runoff. I have properly ph-balanced nutrients. I used to check and then spot check the first year or 2 of growing. I stopped doing it and in 5+ years never had a pH drift problem or a runaway EC. Doing things the "right" way avoids it. What i put in is not what i expect the reading to be. I expect it to be consistent -- the resulting equilibrium of my fertilizer mix over time. As long as the 10% runoff is relgiious, it won't drift. Again, i do not expect it to be exactly what i put in. In soil it's not so cut and dry, so you may have a greater need to keep track of this stuff, but form a baseline of "normal". Don't expect it to be what you put into the soil. The only way to use such runoff testing is to know what "normal" looks like when your plants are supremely healthy and rocking out. that's the runoff values you want to maintain. This stuff can somtimes takes months to show a problem, so have a long memory when you set this baseline. From then on anything deviating too much is a problem.

Hello Mastr, the plant does look healthy and with those numbers it would not. I would not flush or change anything because the plant does look healthy. Keep giving it the same amounts as you did before and only water in between. She does look great with beautiful buds upcomming!

That sounds crazy high, are you sure salt buildup in your drip trays aren't pushing those numbers a bit higher? Judging runoff out of soil isn't as clear as soilless substrates, it could just be other microbial growth that's actually beneficial. Trust your eyes. If the plants are loving it then I wouldn't worry.
