Grow Mediums calling all dwc heads

Hello beautiful people, thanks for stoping by. Planning my first ever dwc grow. Water is quite hard in my area ec 0.4 should I treat this as 0 when adding my nutes or should I take this into account? What do you guys think thanks in advance

good question bro im in the same boat as you and would like to know the answer, but unfortunately i have a lack of knowledge on this subject and am unable to answer :dunno:

You can kinda disregard the background EC when making up your nutes ,but obviously your meter will read that background EC as well ,so it up to you to subtract the BGEC from the meter reading & you will know the proper reading .The 0.4 in the water are probably inert & you shouldn't get any tip burn or signs of overfeeding because of it ,unless you have really nasty tap water !

Not sure if that was helpful lol .If someone with RO / zero EC water wanted to start seedlings at 0.6EC , you would start yours at 1.0EC but the resies would be same

Im stonded ,im outa here ,goodnight folks

Ya may luck into not haveing to add cal/mag too. Just watch for toxicity signs if its city water keep checking it cause they do change that. My ppms in florida varied from 100-300 and would change overnight when I let it set for the chlorine to evaperate.

I would take it to account to a point. Optimal ec level is such a strain specific thing too. I have had grows when I never have exceeded 1.2 ec and grows where the plant had required up to 1.8 ec. As a rule of thumb it might be better to rather go too low than too high since as far I understand, too high ec really stuns the bud growt.

Somebody more enlightened can correct me but wasn't it about the root systems ability to suck up water and bring it up along with nutes that gets a bit compromised if the EC was too high for it? Therefore more lower EC would give better flow of the water from tank to plant.

I am still quite nooby but for a long time I was doing far too high EC on my plants. Now I know better... it is the light that is the main dinner for the plant here.
