think ill just give her a basic bloom nutrient after the flush

what I dint know is when should I feed after the flush ?
Directly after or should I wait for the soil to dry

I would only flush if there was a buildup of nutrients in the medium. If that's not the case I would probably just give it straight water but this too is only if it's called for.
pH can make a difference here and while soil usually provides a buffer, a soil with pH well outside the desired range can cause nutrient uptake issues and this displays just like a deficiency. This is just one example, unfortunately without more info on what happened and how you got here it makes it hard to determine.
All sorts of things can cause yellowing but I can tell you it is something to do with something happening in the root zone because of the location of the yellowing. It's probably not light burn. Personally I start with logical small changes and work from there but I also know all my info.

Honestly its my first grow and I fucked up from the beginning
Im using a pre fertilised soil so I didnt know when/how much I needed to feed

Not well enough clearly. You can use whatever strength you want, what you need to keep in mind is the EC of the solution before you use it.

basically half strength or diluted 2 times would be 5-5-5. well not quite because that 10-10-10 is the percentage of npk in the salt form right? i’m not a salts guy. so if you dilute it 2x it would be as if you were giving a full dose of 5-5-5 ferts.

oh god checking ec and ph is my nightmare. especially maintaining ec and ph pens. one of the many reasons i do organics :D
 
Organics has its own set of challenges. Soil can’t hold a candle to the growth rate of soilless either.

The NPK ratio just gives you volume. No issue using highly concentrated nutes. Hell, you could use just 20-10-20 the entire grow and be fine. All this shit breaks down the same whether you’re using synthetics or organics.

Also EC/ppm pens don’t really go out of calibration so not sure what your point is. PH pens do though.
