Over feeding takes many forms, dependent upon what they were overfed to begin with.

All I can tell you for sure, is that those plants have absolutely no business getting any nutes at all. If anything, you want a 5-1-1 fish formula...but even that may be too much for your gumby plants.

If your plants dont have enough foilage to use the nutes, what happens to them????

I dont nute for the entire veg stage...up to 60 days. Good growing medium and proper pH water is all you need.

You gave those plants a pretty strong mixture of nutes that is cannot possibly use at this stage.

Just keep the sun on them, spray mist them with water, keep the bugs away and let nature take her course.
