Starting feeding nutes too soon PPM 4000

I started feeding my autos that are in FFOF soil too early. I read bad info and fe
d Grow Big at the end of week 3, about a 1/2 teaspoon in a gallon. This was only one feeding the rest was phed water with cal-mag.

Today I gave phed water only and tested the runoff. It was 3900 ppm. What can I do next to help my plants to recover from over feeding?

You could start by measuring what you put in ppm/EC, rather than trying to measure runoff.

I will moving forward. This is my second grow and I'm still learning a lot by fuck up. We're at the end of week 4 and showing preflower. Should I flush? Since it's so high?

Ive always wondered what my cooked organic soil would read in runoff ppm,assuming it just what's in this guys soil thats reading so high? Unused organics will turn to salts won't they giving the high runoff ppm?
Ive seen this FF soil,looks like it came from a field behind the barn lol.

You think that's scary? Try buying "premium hydroponic grade, triple washed Coco coir", all to run through your first feed at 400ppm, and the runoff comes out dark brown at 7000ppm.

I was trying to explain this to a mate using Super soil. He's done a runoff test and it was in the 3000s and he was contemplating running like 50L of water through it.

Then I asked him why he's testing runoff TDS with every watering in a super soil, and ends up he's feeding salts as well.

It's criminal how many people go for an organic soil and immediately feed salts from week one, basically nullifying the organic soil.

I agree. Fox Farms makes decent organic soil. Then they sell people chemicals to throw on it.

These conversations never end well though, lol.

I run the my tap water through a filter and ph it to about 6.2. I've been adding a 1/2 teaspoon per gallon of calimag
Those plants and pots are big enough that they'll absorb and eat your mistake no problem...just stop doing that feeding stuff for now
