Hello, thank you for answering. I use city water. But the ppm of the city water is very high here. I did not add any fertilizer, I just lowered the pH. With a pH of 6.8 ppm 400 500

If your run off is that high then you need to flush. And you need to get a Reverse Osmosis rig to clean out your tap water, can’t be having that high a ppm without nutrients. I suggest you research this more, plenty info online

You reduce the ppm by adding less nutrients to the water. What’s the ppm of the water your putting in?

Flowering nutrients - BioBloom, Top Max, Alg-a-Mic - from when on?From when on do you start giving this nutrients? I'm considering to start Thursday, beginning of week. She looks ready for it, and I believe it'll be favorable for her growth in this stretching stage. Also considered to just increase the amount of the veg nuts. What would you do?
