This seed showed tap root on 2nd day of germ. It seems to have a good vigor as you can see in the pictures first leafs have grown a good bit. I have not given it any nutrients.
@Thekreeator, I do soil, so I'm not sure how much to use in DWC, but my measurement is 4ml/gal of CaMg+. I think it is a hydro supplement, so that measurement is pretty universal. All in all it depends on the nute. Also, I'd probably keep the temps around 75-77degF, and the water should be cooler than that. Plants have a hard time above 75degF unless you are adding CO2 to your grow room.
@MovingOn, thank u I was thinking to add just mag but I feed it calmag and was worried about over doing it I have about 4 gal dwc how much do u think i should add thank u for helping
