What medium are you growing in? Looks like something is locking out nitrogen.

Happy frog been using Jacks ROblend with epson. 4 th week of flower iknow the tds is high @BobbyDigital
The tds really isn’t that bad. What mix of jacks are you using? The typical 3.6, 2.4, 1.2?
Jacks ro blend is 12-4-16 + epson 6.31 g per gal +.99 g per gal i’m in 7 gal pots usually water 1.75 gal per watering every 4 days with good runoff
I’ve only used the Jacks 3-2-1. That phosphorus (4) seems really low to be used by itself. Even the nitrogen (12) seems low. My part A is 5-12-26, part B is 15-0-0. Then the third part being epsom salt. Do they recommend any other supplements with the RO?

No just epson. Last watering i used just Flower Fuel 1-34-32
Is that the only time using a booster?
Yes it was the first time. i’ve used it before and really liked it. I just can’t understand why i can’t get the ph to raise. Really thought about ph to 7 and don’t water to runoff
Your ph is fine. Just feed where ph should be. It’s the ph buffers in the soil that are giving you that runoff number. Fox farms seems to buffer down to the 5.8-6.0 range. Alternate between your jacks and booster on feed days. I wouldn’t mix them together because I don’t know how they’ll react together. Think you’ve been lacking some P and K. Probably some N too.

Yeah i didn’ t mix with Jacks just Flower fuel ialso thought i needed more Pand K
To get your PH readings more where you want them, could try to water for run off more frequently.

I grow in coco and water for about 25% run off. Like a mini flush my readings when I spot check are fine.

I"M in straight happy frog
Don’t see where soil would make a difference the plant will consume the water. Does it matter if there’s a quart or a gallon.
I agree

What are you using for ph down? Silica really hikes up the ph
I really can" remember off had maybe general hydrophonics . But i ph everything that goes in
