I got a bag of soil. Organic. I always start about 10 seeds ineach . thoselong planter boxes. After they getgoing i move them to small pots. I didnt like the soil so igot some different name brand stuff. And planted more the new soil ones jumped out of the gate but the old soil ones just stalled the stems started turning purple icould tell there not growing so i transplanted to new soil now there almost caught up. I dont know what but new soil might save them .
