Leaves yellowing with marks please help

Have you tested the runoff water. A ph test and ec test of the runoff should tell you what’s going on if you can collect enough of it. I don’t know why that’s not the 1st suggestion. Water that has ran thru soil of any plant should be better than guessing? Jmho. I’m new here. But that just seem logical.... esp if you try it with distilled water that you know the properties of before you pour thru.

Without knowing what his feed schedule is or if he’s ever fed to runoff I assumed his runoff water will be off the charts. It always is if there’s been too much added and no schedule runoffs.plants wouldn’t look that bad had he given regular runoffs. Regardless of what his runoff is and if his plants look like the other pic then it needs help.

Alright let’s start doing it the right way what ppm should I put in and what ppm should I expect in the runoff?

ok so quick check autos are fine to flush.Now depending how messed up the soil is will determine how much.So you can just use ph water say 2 gallons then give them food on the last 1 ltre.

pH and EC only tell you so much. They can't tell you what specific nutrient levels are. They said they were using the full AN lineup. That's what 10-12 different bottles of stuff. That's what's causing the issue which is why I recommended cutting most of it out.

So give them ph water test runoff like a litre or so report back.My guess is 2347ppm lol
Alright I was in bed couldn’t sleep and before I saw your message I ran and watered them 4 liters each with 6.5 ph and 1024 ppm and had run off 6 ph and 1540 ppm
I put in there only quarter base nutrients and half dose calmag

I really appreciate all of you guys sharing your knowledge with me and trying to help me

ok so thats pretty high.500 ppm is 1 EC on a .5 scale pen.You should be feeding around 5-700 ppm.

So thats just base nutes yes? so ph some water and pour until runoff is much lower, may take 5-9 gallons.

Yikes! What the hell is in your water? Is this from a municipal supply and not a well? Do you have a water quality report?
I would have told you where I live if it was legal here but our water are excellent it’s either because they add here minerals either because my pipes pretty old
It’s not uncommon thing to drink tap water from the sink here

You can cut the calmag out. There's going to be plenty in 570 ppm water.

So I gave each of them another 4 liter with ph 7.4 to raise the ph and 570 ppm and now the runoff somehow came ph 5.7 and ppm 1100
I assume the ph stuck because of advanced nutrients ph perfect which balance the ph to 5.8 and everything is chaleted so it absorb anyway
So you think I successfully brought the soil to safe nutrients level?
