Hi there.. that depends on your environment and how your plant can handle it.. if you slightly under-feed with your regular nutrients, then you can try adding the booster and raise the total EC a little.
If your plant is already being fed perfectly, or on the higher side, the extra EC might be too much for her to handle.
My white haze grow has very very lightly burnt tips, because of exactly that.. she's fine with 1.1 to 1.2 mS at this point (i grow her in a hydro-DWC setup and measure EC of the nutrient solution daily), but when i change the reservoir once a week, and add the boosters, she gets around 1.4 mS, which is too much.. that's just in for a day, as following that, i top up without the booster and over the course of a few days she drifts down again.
If i followed the instructions on the back of all my nutrients blindly, she'd get an EC of 2.9, which she could never handle in this environment (under a single 50-walldrawn-watt COB), and i prefer my plants rather to be healthy than overfed.
happy growing!
