there were 21 clones, at 10 days they all looked great then they started dying. the ph was about 6.8/7 yes we cut at an angle under water and used rooting hormone powder. i used a dome for the first week or more. most of them showed roots coming through the botom of the cubes which came from a slab. the cubes eventually got some green growth on the top of them
i did not moniter the temp or humidity, they sat on the kitchen counter by the window (morning sun) for about 2 weeks.
I foiler feed them with a mild solution of something my buddy gave me, Ill have to ask him the name.
I do think it was nutriant or ph related what ever went wrong. My big plant is starting to flower now so I think its too late to get more clones.
The big plant i grew in Recipe 420 soil and feed mirical grow tomato food, noe I am feeding it scotts super bloom abot 2x a week, the fan leaves are starting to yellow, it just gets tap water ph is over 8. soil tested neutral. This is a sort of warm up, my first grow in many years. I want to get into it.
