Hi

I already asked similar question but with Coconutz being gone, the answers are just not there.
I want to refrase.

Vegge in cubes - the stalk and main cola are very thin but the foliage is very green and vigorous.

Vegge in coco - the stalk and colas are much thicker. Foilage less greener.

Anyone knows or understand why?
Can't seem to find an answer.

silica content?

ph is low on the rockwol and lets nitrogen be absorbed more efficiently?

ph is high on the coco, less available nitrogen?

rockwools too wet?

Also possibly because of the coco leeching calcium and other things, as well as the pH diff.

Hello mates. I am rocking 6/9 formula right now.
Flora Micro/ Flora Bloom. 400 ppm with 6 ph.
No additional adds.

Not in coco yet, brother.
I will transplant cubes in a week or so.
Then 6x9 should do well. I use Epsom at times but only when needed.
