Yellowing leaves top and bottom help

Running promix hp. Nutes are 1.7ec average over last 2/3 weeks. Day 45.

Check runoff last feeding and it read 3300ppm/4.5ec. (Feed giving was 1200ppm/2.4ec) so not sure if that’s part of it. Ph of runoff was 6.6, intake ph with nutes was 6.4.

read to run a slurry test but no clue what results means lol.

Plant 1— 330ppm-6.8ph
Plant 2–140ppm-6.7ph
After 10min...

And then after 40min

P1- 290-300 ppm
P2- 200-220ppm(both bounced around when I took meter out). Ph was

Is the runoff 330 or 3300 cuz you've mentioned both numbers above, because you're not going to have runoff of 3300 but a slurry test results of 330

Are you feeding NPK or did you cut/drop the nitrogen?

1.Feeding bloom nutes 2 part.
2. Slurry test was 330ppm..
3.Runoff was 3300 with a feed @1600ppm.

Yeah I figured you dropped the N from your pictures, your plants look ok, just starved of nitrogen; recommend feeding a balanced nutrient all the way through bloom, good luck.

Yeah I run for a flex b1/b2 and idk what’s going on. For whatever reason not eating from roots only from leaves. Was hoping someone had an idea. I thought N def too but still have no idea how/why ect

What do you mean you don't know why?? you said yourself you were only feeding Bloom nutes, that's why your plants are lacking nitrogen friend

Like I said above above, the fix for your problem is to feed balanced nutrients which include nitrogen through the whole bloom cycle

I’m feeding “bloom” nutes in bloom. But they have nitro in it. It’s a 2 part feed.

14 0 22 then 0 28 18

14 28 40. I suspect all the K will lock N up for sure!! Too funny!

My guess is you have a nute imbalance...your EC is pretty high! Did you flush like i said to?

Flushing will happen today. I just fed other day soil still was wet. And ec for feed is right where they recommended, and has actually been lower than what they call for. I know a few people running the nutes not having this issue pushing their ec up towards 2.8-2.9

The ratio for floraflex works fine, or at least it did for me. But the ec recommendations are way high. Never went above 800ppm with it indoors myself.

Personally i think youre overfeeding with runoff numbers that high.

Is the N nitrate, ammonium?
Is there calcium in the nutes?

If its nitrate with cal and you have that much K im starting tobthink that its a basic nute. Meaning more alkaline, its going to push your ph up

Im not sure the breakdown the N sources, but it was incredibly stable for me in the res and the runoff. Ph never drifed at all.

Never got that far with it. I fried that crop halfway through flower accidentally unplugging my extraction fan, and switched to organic for the next crop for shits and giggles
