My grows almost over and I'm out of soil but I have some good quality coco soil was thinking of giving it a try. I'm planning on using the general hydroponics trio for nutrients with molasses from mid to late flower. I heard you need to use calmag when using coco but I have no clue if that's true.
If you can answer any of these questions that would be great:
1. Should I use perlite or vermiculite and if so what percent of each?
2. Is the calmag necessary and if so does that mean I have to tone it down on the other nutrients?
3. Coco is pretty soft so can I not transplant with it?
4. Can I place the sprout right into the coco or do I need to use something else until its a seedling?
5. Is there anything else that's different when using coco instead of soil?

1/Perlite your choice . More perlite more frequent watering . Vermiculite not really needed .
2/no you mix weaker generally so just add the recommended dose.
3/yes you can once roots have spread into it.
4/you can start them in coco.
5/ dont let coco go dry it messes with the ph, and feed with every watering . Coco is hard to overwater. You can get faster growth with more feedings .
