If you are running something like promix hp then I would run water for the first week (being careful not to overwater), the seed will have enough self sustaining nutrients for the week or so of seedling stage.
After that I would consider the second week as week 1 of veg and try to feed based on the feed chart, adjusting as necessary.
First week of veg feeding
1ml/l of micro
1ml/l of grow
1ml/l of bloom
I would feed that mix until I get some runoff then the next time plants look thirsty I would give straight water until I get a small amount of runoff.
2nd week:
2ml/l of each micro, grow, and bloom. Feed to runoff, let soil dryback and hit with water. Adjusting feed or water based on how plants look.
3rd week veg:
3ml/l each
Same procedure as last week
Week 4 veg
4ml/l each
And you guessed it, feed, water, adjust as necessary.
Then continue to follow the feed chart ( https://www.advancednutrients.com/feeding/ ) adjusting as necessary. It's hard to tell someone how to feed, as each plant has different wants and need, environment plays a large factor on what they want as well. Things like heat, humidity, light intensity, air flow, pot size, strain, pot type, etc will all change how the water and feed cycle go.
Another thing worth mentioning: although I'm not 100% sure how advanced nutrients formula is I find with LEDs at high intensity and the couple of nutrient brands I have run I need to add cal mag to the waterings in between feedings to help prevent deficiencies.
Good luck and happy growing.
