Well I know if the leaves are turning yellow they need chelated iron.
But do you need to prune them or train them a certain way to get the most fruit out of the plant?
Hi Albert. IMO you do need to prune indeterminate plants. Here is a link to a video I did on just that process - http://www.youtube.com/user/aquaponicgardening#p/u/13/amIhZnKEPp0. Let me know what you think!
Hey Kobus. Not sure what to tell you buddy on the nutrient front. They kinda grow like weeds for me, although they've been being attacked by aphids quite a bit lately. Are you rolling with 12" deep beds? I've also noticed that when things have gotten clogged up and haven't drained well that the tomatoes have taken it harder than most of the other plants. They Really seem to hate wet feet. Can't remember the specifics of your system. You are siphoning pretty frequently, right?
Thank you Sylvia, that is super useful to me! I reposted it, if thats okay.
