Risk of loosing rare strain! Please help!

Hello I have a small bubba breath clone, I don't really know much aabout cloning and all of my clones died except this lady. She was struggling in the beginning and took almost 3 weeks to root, I was just using small Rockwool cues and wwatering with drinkining water, once it rooted after 2 weeks it's only grown a few cm, I've had this plant for almost a month and a half. It is about an inch and a half tall. It is very light green and there are really no blades on the leaves light green and I notice lower leaves yellowing and dying even if I trim off the others die. Sorry cant post a pic but it almost looks like a basil plant minus the way the leaves droop if u catch my drift

do not overwater rockwool

Clonex has a nutrient mix just for clones. It sounds like overwatering or it's hungry.

Thanks fir the feedback, I've switched it into my grow box and am now watering with flora nova grow , I transplanted into 5 gallon buckets, I'm thinking about moving this one into the dirt in the woods behind my house .

I went out and bought clonex Will use it.with next watering
