Seedlings and coco questions???

I have done one coco plant by starting a solo cup of happy frog/perlite, and then transplanting into coco after the seedling was substancial to sucess. My question is how to start the seed in coco and mature it. The coco I have is pre washed and buffered with perlite. So do I just moisten it with PH’d 5.8 to 6.0 water with a light dose of calmag? Then add seeds and water in. My concern is that there is no calmag or nutrition. When do I start adding my coco A/B nutrients in micro amounts? Shouldnt I always have calmag in plain waterings u til then?

I just water full strength from day one and they're always fine

I pre-moisten the coco with a light nute solution (just calmag is ok also). Plant seeds and they should sprout in 3-4 days. I start feeding daily to run off starting around day 3 from sprout, and transplant after 2 weeks.

The need for calmag at all depends on the water source.

As for nutrients the seed has it's own store of energy, so there's no need to stress too much.

But as these chaps have said, you can start feeding if you want, but it won't die of malnutrition if you don't.

Unlikely that you need to add CalMag...Depends on your water/fertilizer...Plant should be in a Solo cup until you see roots at the drain holes. Strong roots are an indication that the plant is healthy. Feed every watering. Transplant into final container after Solo cup is well-rooted. Give it more/better light.

I use the Jack's 3-2-1 fertilizer and I use it at their recommended dose. I've never diluted any of it.

Rapid rooters are popular, never saw a complaint.
