Noob in hydroponic. Nutrient question.

This is my very first time doing hydro. I am using a 5 gallon stealth hydro DWC setup. Im currently on my 6th week overall, 2rd week since the switch to flower. The only hydroponic nute I can buy locally here is a mix used for SWC which I am very happy with. I have been following the instructions in the bottle, which doesn't require me to do anything but replenish the reservoir water with 1/2 strength nutes. I have not totally replaced water, I just keep replenishing it and so far, in my 7th week I have been problem free w/o checking the PPM and PH.

Now my question is, do I just keep doing what I'm doing? I just got some AN SensiBloom and I'm thinking of using this now, but I am having second thoughts since I have not experienced any problem with my local no-name hydroponic solution. Any input would be welcome.

Without knowing what's in your first nutrient solution it difficult to say, but if you bought the Sensibloom specifically for flowering then changing to that should be fine. I would change the whole solution out if you are going to swap over though.

Looking good apart from that
