If they were growing OK initially (in your own garden) then it would seem the soil pH is already suitable? I'm not a fan of fertillizing new transplants, if you use too much it can actually make it harder for the plant to take up water, and the root system will already be compromised by the transplanting. Both products are fertilizers, manufacturers like to call them "food" but plants make their own. Did they need to be moved for some reason, just to help understand the situation?
