Hey not to beat a dead horse but based on this one bit of info you gave the opinions will be varied and more of a guess. If you kept a log or even continued one of the many other threads for the same grow you have on here there would be less questions to answer from people who need more info to help you.

Like soil/lights/environment and other variables. Simply thing to say without any of that info is ease into feeding if you haven't up to this point. Some strains hate anything other then good soil and PH'D water like Mandala's Hashberry as an example. Using different nutes for the different parts of the plants cycle is nice because you then can do things like promote more budding sites or stronger healthy root mass. You being 3-4wks in flower won't be doing that by starting to feed now obviously, but you will be able to max out what potential the plant may have based on its condition now.

I would dilute the stuff your trying to use at least in half if not more and slowly feed your lady. It would really help to see what the leaves and buds look like at the stage your at. Mine are about to be in wk 4 of flower and have already shown signs of ripening for their life cycle like yellowing slightly can be normal for some strains. I wouldn't want to shock or stress what you have at this point because if you throw it out of wack you might be cutting it close to not having time to bring it back in order and flush out nutes etc before harvest. Snapping and crackling herb is not healthy..not to worry you just saying that's what I would think about overall before you over think and do anything with nutes with little to no experience in your 3-4wk of flowering. Check my last log out if you need a good laugh or example of a plant going into nute lockout and running out of time to make changes.

Its kewl you keep asking questions it shows you care about what your doing but if you log it you will be able to look back to the things you have encountered and learn from that and the help people have offered and maybe someone else can learn by reading and watching your log. This place is very helpful imo. Happy gardening! sorry for long post and run on sentences!:hippy:
