Death on new growth like this is usually caused by one of 3 things: frost, some sort of weed killer spray/drift, or nitrogen burn. There are other possibilities of course but can you rule out these 3 as possibles? Dave

Spinach is subject to all the same fungal and bacterial diseases as most other garden vegetables. Yours looks like Septoria or Cladosporium Leaf Spot to me because of the brown spots with white centers. Septoria is the most common. But it can be difficult to distinguish from other fungal diseases. See the link below and scroll down to the Leaf Spot section and Google pics of Septoria to compare. Treatment is a preventative use of fungicides. Dave Here is a link that might be useful: Spinach Diseases

Hi GreenDreamHome: Perhaps the previous home-owner over-applied fertilizer to that rose. Some roses are more susceptible to salt-damage. Knock-outs can take salt-abuse, but certain roses can't. The 1st picture looks like fertilizer burn. I got the same when I mixed 1/2 horse manure into the planting hole .. horse manure has high pH, plus 10% salt. No amount of rain could undo that, so I had to replace the soil. Luckily the rose was small, so I could dig it up, rinsed the root-ball in a bucket of water, and planted in new soil. Someone in Florida once posted similar pics of leaves with big brown spots .. she mixed 1/2 cow manure (alkaline & salty) with her sandy Florida soil. I did that to my lawn recently .. there was left-over soluble acid-fertilizer 32-10-10, so I used a flour-duster to sprinkle on my lawn. I spilled a bit, so there's this big-brown-spot .. still there despite this rainy month. The second picture looks like my Sharifa Asma when I over-dosed on molasses (high in iron). Same with last year when I gave Gina's rose soluble molasses without watering her first. The molasses-brown-spots are easy to fix: tons of watering, the Gina's rose was OK ... when I dug her up to give away, the roots was huge. In hot climate, the soil tends to be more salty. I don't fertilize when the temp. is over 80 degree, and if I do, I water first, apply very diluted soluble, then water again. If your soil is rock-hard-clay and very alkaline like mine, then gypsum (22% calcium, 17% sulfur, and 8% salt) is recommended to break-up heavy clay and to de-salt ... best used as soluble in cool temp. If your soil is loamy, sodic (salty), and less alkaline .. skip the gypsum. Good luck with your roses ... the second picture is easy to fix. The first picture, if only a few brown spots, lots of watering will do. But if it's over 10 brown-spots like what I did, then I had to replace the soil.

I am growing tomatoes indoors under a HID light in soil. I am really new to this and have virtually no experience. Anyway, all of the sudden, my tomato plant started to turn brownish purple at the soil line and just above. I assume that the plant would have been permanently stunted or would die. Can anyone identify what is going on here? Thanks! Image link:
