I don't know enough about your grow to say a definite yes and if you're growing in coco I have no experience w/ coco but I do know that I need Calmag w/ every grow and most growers use some form of Calmag ... yellow tips could be a sign of a lot of different problems ... might be a good idea to post your question along w/ pics in the infirmary section ...

You really should post a photo. The yellow tips normally indicate too much nutrient. If it's getting a little rusty looking, it could be cal/mag too. One of my plants get A&B, but I also use cal/mag and organic Blackstrap molasses and Rhiz for that plant .
