Tomato seedling disease -- ugh

terradikaFebruary 19, 2014

Hi, I am growing supposedly disease resistant rootstock, Maxifort so I can graft heirlooms onto them. My seeds are up about 5 inches now but am getting leaf curl as well as the bottom leaves are turning purple and are getting bumps on them. Can't tell if it is a fungal or bacterial problem.. Any help will be helpful.. thanks.. if fungal, will baking soda or asprin help? What about copper?

Probably neither since exposure to both bacteria and fungal virus while growing indoors is extremely rare as exposure would be difficult.

The purpling is common with young seedlings with young roots when growing in cool environments - especially if watered with cold water too. It is a normal physiological response for the seedlings and disappears naturally as the plant matures. It requires no intervention 95% of the time.

The bumps are on the leaves or the stems? On the leaves it is usually water blisters from over-watering and disappears as soon as you cut back on the water and/or humidity. If on the stems they are called adventitious roots and are normal in older plants - very common with Maxifort. In young seedlings it can also be a sign of over-watering.

Would need much more info and hopefully a pic to be more specific.
