im in my fourth week of veg and added bluemax part a and b at 2ml each and 3 ml cal mag witch gave me a ph of 7.0 and a ppm of 553. I fed a whole gallon then checked runoff and tested at 6.3ph and well around 3,000+ ppm what do I do in this scenario?

That’s the soil Iam using and i added the nutrients yesterday so should I wait to flush the plants to avoide killing my plant?
More info is needed to diagnose the issue. What type of soil are you using? Soil like FFOF comes amended with organic nutrients that take time to break down and become available to the plant roots for uptake. If you are using a soil like this the ppm run off reading will be high but its ok because its not readily available to the plant yet.
the bend is from LST. And I’ll most Definitely do the 6 gallon flush to lower ppms Thank u.
It maybe that you are killing the plant with nutrients. My humble suggestion would be to stake up the plant and flush with pH 6.5 distilled water (6 gallons) and look for recovery. This plant still has potential, don't give up.
