How often do you add nurients to plants

I am using Aurora 707 soil. In my 3rd week of growth. They say thye soil has nutrients for 4 weeks.
How often do most people feed Photoperiod plants. I have been on a autoflower kick for past 2 years.
But the summer has lasted longer and I needed to wait for cooler weather anfd will only grow one crop this year.
SO I wanted photoperiod.
And I am just asking a generaslized question. I realize things change as you go.
Thank You,

For Chemical fertilizer-I feed smaller than recommended max dose, every watering. I start at 10% strength, from Seedling stage, and SLOWLY work the feed higher, and I try to use the Least amount of fertilizer possible, that will keep them happy, and healthy.
Also consider I use Promix BX, which has no fertilizer in it.

For Organic, and keep it extremely simple- Id use Gaia Green, 4-4-4 and some Azomite. I MIGHT add some Gaia Green 2-8-4 - 1/4th of the way through flowering, ( 60 Day Strain would get dose at day 15. ) and would still use the 4-4-4 on the scheduled 1 month intervals.

I use Jack's 3-2-1 system and I feed their recommended doses every time I water in soil less mix such as FFOF and the like. After a month, most soil less mixes are exhausted. That's great to get through the seedling stage as well as the first couple weeks of veg. But, after that, it becomes a completely inert substrate. It's essentially a drain-to-waste hydro system.....It just looks more like dirt than some of the other hydroponic substrate options like rock wool or hydroton. But, yeah, feed full strength every time. I use a LOT of light, a lot of fertilizer and I end up working around the plants a lot...so they get a decent dose of my exhaled CO2.
