if you can, i'd switch over to rapid rooters next run. they are much more forgiving than rockwook in my opinion.
When do you add nutes in hydroponics

No man, that works fine. Again, just my suggestion, I would be feeding 3 ml per gal of your nutes and 6 ml per gal of a cal/mag. This is to start, then slowly increase proportionately each week.

Cotyledons for dicots like cannabis contain nutrients from the endosperm for a seedling.That two week thing is fine for seedlings sprouted in real soil that has nutes in it but for hydro only it needs nutes right away. How does nature withhold all nutrients for two weeks when a seed sprouts out in the wild?
Starving a baby for two weeks after birth is ill-advised as well.

Wow 6ml of calmag as well on Top of the regular nutes? Seems like a lot but maybe I’ll barley do both

That's starvation rations for the seedling that can absorb and use nutes from the roots right from the start like it would naturally.
I usually sprout my seeds in small 9-hole seedling pots filled with ProMix that I've soaked good with seaweed ferts or a low dose of 3-part. They can go a week or longer before needing any more water and would not do as well with no food. I keep them in a humidity dome until true leaves are well formed. If destined for DWC then it's the 3-part nutes. Organic stuff in DWC seems to lead to root rot issues.
With 18 hours of good light per day they can do a lot better than they could waking up in the cold ground of spring in the wild and need food for the energy to do well.
Sprout a seed in fertile media and one in rockwool then give both nothing but water for two weeks and see which does better.
Two weeks with nothing but water for a struggling seedling of any plant variety doesn't make sense. Fine if it's in real dirt like I've said before and mostly that refers to people who've planted in good soil and asking when to start feeding nutes on top of what's in the soil.
I'm liking these 3" flimsy little nursery pots better nowadays. 18 fit into the standard seedling tray and the sprouts seem to do way better when started in the larger pot and can get a good size then go straight into a 4gal until the end. I bought 8 flats of 18 a couple years ago so all stocked up.

I answered your question, I wasn't proposing hydroponic best practices. No argument was intended.

While your results speak for themselves, I have not had much luck with early feeding with the stuff ive grown. Every time ive tried to feed my nutrient even at like 1/8th, they are obviously unhappy. Of all the variations ive tried, this has been whats worked for me and ive just stuck with it.
I popped these 3 skywalker og seeds on around the 12th of jan.
They are still at 200ppm of tap, calimagic, and dyna-gro KLN/Pro-tekt combo in the cloner because im lazy and need to finish their box tomorrow. Roots are a foot long and tangling up in the bottom of the box. Only thing theyve shown was the spots which stopped with another ml/gal of calimagic.

If you have a5 gal bucket with 3 gal of water that's 10 ml of nutes and 15ish of. Cal mag. That should get your pH down to 5.7range and they'll have plenty of what they need for the week.
