Deficiency?

I have not been, this is end of week 3. Next time I water I will do 1/4 gallon to try and get run off to measure both. I have been shooting for under 5.7 for PH but may start going higher. have been doing 1/8 nutes but this week went to 1/4.

I did a little less than 3/4 gallon today each plant , PH 6.5-6,6, 1/2 nutes aurora grow, used moisture meter and much better, they were dry (guess 12oz every 3-4 days wasn’t enough), light moved up again to 24” due to growth, LST done this week, run off ppm between 520-650 a bit high, how can I bring it down?

@low rider auto How old is the plant? Are you following the PPM cheat sheet in my book or video course?

Watered two days ago, ph 5.6, 1/4 aurora nutes, 81F 55%RH 12oz last water
