Hi, my tomatoes (unsure what variety) probably indeterminate, started well, but now Im seeing what I think coild be fungi or bacteria on both leaves and stems. I also notice it on the aluminium Arial tube that I'm using as a stake and some if the nearby wooden framing . I worry it could be septoria, or worse fusarium but hard for me to tell.ive been fairly careful to avoid getting soil on the leaves. Any advice appreciated. Thankyou
Being as how this mold is on everything it has to be a weather-related problem. I don't know the weather where you live but it appears to be extremely humid and this will lead to a tomato plant problem called Tomato Leaf Mold. About the best thing you can do is separate your plants and provide much more ventilation with a fan. I would also spray with Neem Oil as it is a fungicide. Also, your tomatoes appear to be yellow-green, not a dark green which is indicative of a lack of proper nutrients.
