lack of nutrients or little over? (please help)

My seedling is showing signs of yellowing? Not sure if its under fed. Im using a quarter strength of an A solution in dwc bucket. Should it be half strength? Would this be my problem, plz help

There is salt build up on some of your hydroton. Personally I think you have moved these too hydroton too soon. I use a dwc cloner and wait until I see roots and the stalk can be placed on the bottom of the net pot and filled up to the rim and still have leaves generously coming out of the top. Here is one of mine that I would not transplant yet.



After I see healthy roots like these I add a small amount of the regular nuit schedule and let them start to grow up. After they are tall enough I then move them to their more permanent net pot.

Started from seeds dude, how do you recomend dwc with seed. Also how could one clean the salt build up on the hydroton? Thanks

Botanicare Clearex, or a light nutrient solution flush will clear up salt buildup. Be sure to clean your hyrdoton in between grows! Hot water, and h202 soak with ph'd water for at least 24 hours.
