I use cal/mag after about 2 weeks to 1 month . Cal falls out of soil eazy when you water and led seem to add more need for it also.Check you Ph and soil content to see if you have good soil mix.
Cal Mag Additives
Calcium and Magnesium additives are specialized nutrients designed to compensate for deficiencies in most nutrient and fertilizer schedules. Calcium and Magnesium (often referred to as Cal-Mag) is almost always needed when using pure, distilled, or reverse osmosis water. Tap water almost always has an abundance of Calcium and Magnesium in it. Calcium and Magnesium are the most abundant minerals in tap water. The majority of the PPM, or EC reading, you obtain from a measuring device is cal-mag.
Calcium, an essential part of the plant’s cell wall structure, improves the absorption of other nutrients by the roots and their translocation within the plant. It activates a number of plant growth-regulating enzyme systems; helps convert nitrate-nitrogen into forms needed for protein formation; and contributes to improved disease resistance.
Magnesium also helps to activate specific enzyme systems. Enzymes are complex substances that build, modify or break down compounds as part of a plant’s normal metaboli This will give you an idea of the importance of cal/mag for all plants and even more so with cannibis during the flower stage.

Not every tap water is the same. Also, there's a lot of different forms of these minerals. Only few are available for plants.
I only supplement epsom salt every few waterings. It's cheap (few bucks for 500g) and last forever.

Hey Beggie, I also use Biobizz and I can tell from experience that your plant has definitely some nitrogen toxicity when I look at your picture. I messed up my two previous grows because of using too much Biobizz Grow...you can check out my Red Poison toxicity thread. My plants never recovered from the N toxicity and developed very small and airy buds because they were stunted from too much Nitrogen and never went into full bloom. Please STOP feeding your plant Biobizz Growor, or else you will experience the same issue as I did. I tried flushing but it did not help at all and my Red Poison was just a waste of space in my tent. I hope its not too late to save your girl.
Regarding Cal-Mag, you should be carefull when choosing the right product. Look for one with with very little, or ideally with no Nitrogen at all because your plants already have nitrogen toxicity so you should prevent adding any nitrogen.
Good luck man, sending you some
Sorry mate, I forgot to add that I do not see any signs of a Cal-Mag defficiency on your plant.

looks like you have too much N in the soil . down turned leaf.cal mag will be more yellow and the big fans will start to go.
