pro mix hp soil and house&garden soil ab line up

Hi I m currently vegging my plants in 5 gallons pots using Pro Mix HP with the house & garden soil ab line from their site. I been hearing that this line of nutrients cannot be used with Pro mix Hp because the soil contain domilite Lime. I been seeing yellowing left at bottom and the top leaves slightly curve upward. I also notice really slow growth on the plants. Should I changed nutrients since I already use pro mix hp????

Do you use ro water? I am doing the same but I use 2 bags of roots organic to 1 pro mix hp and add cal mag and great white or orca and have great success.
