These are Little Napoli tomatoes. I started these growing a few weeks ago. Everything was going great…then I think I mismeasured and over fertilized. The lowest branch on them pulled off with no force. The water yesterday morning read ph as 5 and ppm of 1000. I did a full change of water and two caps of AG yesterday morning the ph read 6.4 and 500 ppm. It drooped a bit from cold water at first but perked up. However, the leaves still seem to be continuing to get worse crumbling away, and they didn’t seem to drink any water overnight. I also have Calmag I can add but was going to wait a week after AG nutrients. Should I add some now? They look like this  |

I think they will be fine. Let them go awhile. Your pH and ppm are fine at the moment.

Your tomatoes should be fine. Mine usually test at 900-1000 ppm after an R&R, when I add AG nutes, CalMag, and Koolbloom. Tomatoes grow new leaves very quickly, and the lowest leaves should be removed anyway when they're no longer getting much light. Some drying around the leaf edges isn't a problem. When the plant has given up on the leaves, they will turn yellow, and should be removed.  |

Back with my tomatoes today. Had quite a bit of degrading leaves that I went and trimmed up. Put my trellis on the stakes to give the one vine support.  Does this pic look like root rot or normal coloringnutrients? They did drink some last night at least…  |

The older roots look like rot. BUT the younger roots at the top look healthy. The plant looks healthy too.
I think it would benefit from a bit of hydrogen peroxide in the water. Put a teaspoon of 3% hydrogen peroxide in the water about twice a week.

Should I do a harsh prune of the roots? Or would peroxide let them recover?
Oh also, is there a difference between “food grade” and this one I have on hand that’s 3% (target brand).

Hmmm... I'll let lynnee address the root prune issue as I have never pruned roots for any reason. My gut feeling is to just let them go.
I never knew what "food grade" meant on this brand either. I would think the target brand would be fine for this purpose as long as it's a 3% solution.

The brown roots may recover, so I'd leave them alone. I never prune roots unless they have become very dark brown and mushy. Yours are nowhere near that point. My tomato roots gradually turn light brown and medium brown over time, which I suspect--like you--is from absorption of the nutrients. Sometimes you have to leave even the mushy roots alone if you have an otherwise healthy, producing plant. I think that you can use any of the 3% hydrogen peroxide solutions sold in retail stores as AG water additives. Just read the labels to make sure there aren't any warnings that might be applicable.  |
