fertilizer issue rdwc (ı m new)

Hello guys. I have a question about rdwc. This is the system I will get https://www.growkent.com/Harvest-Master-RDWC-6,PR-3625.html. Fertilizers that I plan to use in these https://www.amazon.com/General-Hydroponics-FloraSeries-Hydroponic-Fertilizer/dp/B0B2C22L3G/ref=sr_1_24?hvadid=651117962556&hvdev=c&hvlocphy=906760hm&hvvnetwhvrt34464580hm=34464580hm gid=kwd-119761343791&hydadcr= 23632_13619958&keywords=dwc%2Bhydroponic%2Bsystem&qid=1693395385&sr=8-24&th=1 .
My question is, I will be doing veg for 2 months, will these fertilizer amounts be enough and do I need to buy other types of fertilizer like cal-mag?

Yes, buy everything. You are going to need some cal mag. There is some in the flora line, but you're proly gonna need more. That bucket setup seems steep. What, eight buckets, some hoses, air pump, water pump for more than $150. I'd make my own. I have. I also built in modularity to upscale and downscale to my needs. You might like prepackaged stuff that you are going to fight with, but I like to fight with my own ideas to make improvements that I had already anticipated. Your mileage may vary.

These are my nutrients, pretty much all they had in '96 and I use Micro, Grow, Bloom and CaliMagic. That's pretty much all required. But in pure hydro I'd definitely have their Ca/Mg (CaliMagic) additive.

If possible get a water report. A general guideline is use 0.4EC starting water. If your water is soft bring it up to 0.4EC with calmag then add nutrients. If your starting water is close to that point, you should be fine with nutrients only.

Honestly, imo, the flora series works great, running the Lucas formula, which is just the flora micro, and flora bloom. No flora gro. No need for cal mag either. Google Lucas formula for the ratios, of you're interested.

2 month veg in hydro? I hope you have a LOT of space.

Also, if you want simpler, just get flora nova bloom. It's the same as the Lucas formula, only it's just 1 part, instead of 2.
