Im using RO water, that being said; how long does one generally wait until upping the nute levels past that of tap water ppm?

I have never done DWC before, but I do use RO water for my feed water and since I grow under LED, I always add some Cal-Mag at the very least. I don't think you want to use plain RO for very long, since there's nothing in it for the plant. I would think a mild nutrient solution of 1-2ml/gal would also be a good thing after she develops her first set of true leaves.
Darkwarsongsanswered grow question 5 years ago
You can and should go the first week without nutrients... Do you have bad water in your area? just asking because RO water has very little buffers and fluctuates a lot. It's a lot easier for you if you just use Tap water, but if you live in Flint, Michigan please for the love of god use the RO water :).

PK Boost TimingBy what visual indicators do you determine the ideal timing for giving a week of PK13/14? The stretch seems mostly complete, the buds are thickening daily, and the first trichomes are appearing on the sugar leaves. Should I start now or wait a few more days?

Hello
I will harvest at the end of November.
What are the pros and cons of flushing plants pre-harvest?
Do you believe flushing significantly impacts the taste of the final product?
Do you personally flush your plants, and if so, what is your specific flushing routine?

Early flower and plant too small?Multiple questions: Is this the first sign of flower on the picture of D21 from sprouting? Doesn't the plant look to small for it still? How do I promote new node growth? Is watering roughly about 1.5L per week too little for nutrient influx?

How often use fertilizerHi!
I have a question about fertilization. I use mineral fertilizer from Advanced Hydroponics of Holland (Grow, Bloom, Micro) every time I water. Which can be 2x on hot days. Every 2 to 3 weeks they get worm juice. However, I have now read that you should only fertilize every 2Feeding. Schedule
