When to move rockwool seedlings to dutch buckets

[gdgdad]

Stan, I did indeed make a mistake on the nutrients. In my haste I used the per 5 gallon ratio (1.88 oz p/ gal for ¾ strength) to a per gallon mix in the drum. I discovered this after your post about 9 am this morning - THANK YOU - and scrambled to completely drain the tank, wet-vac out the bottom, and refill with straight water. I also have the pump running continuously to hopefully flush out or at least dilute the concentration. I salvaged what nutrient mix I could with every bucket and container I had that would hold water. Incredibly stupid mistake – hope I haven’t burned them out. This may be a moot point now, but last post I mentioned three tomatoes, one with a black “smug” on the bottom, and two with irregular shaped indention's. The pictures aren’t great (again rushing to beat the rain) but I can re-take closer and clearer if that would help. Any thoughts on those? pull them?
