Downy mildew is caused by Hyaloperonospora parasitica, an oomycete that can damage the foliage and heads of cauliflower. Its spores are carried by the wind and germinate in wet environments with temperatures between 58 and 72°F. Symptoms include yellow spots on leaf surfaces and furry gray mold underneath.

Why is my cauliflower not white?
As cauliflower matures in the field, the sun naturally alters the color of the head. If it is exposed too long to the sun, the curds turn a dull yellow. This doesn't affect the taste of the vegetable — in fact, it likely produces more phytonutrients — but it does affect our desire to buy it.

Brassica oleracea var. botrytis
Cauliflower, Brassica oleracea var. botrytis, is a temperamental cool-weather vegetable. If its needs aren’t met, it can become stressed and fail to produce the sweet, tender heads for which it is prized.
1. Blindness
When a cauliflower fails to produce a head, the condition is sometimes referred to as “blind,” or “blind bud.”
2. Bolting
When a plant bolts, it “runs to seed,” halting growth in its tracks. It’s not uncommon during the early vegetative stage.
3. Browning
Sometimes during the reproductive stage, developing heads begin to discolor, a phenomenon called browning.
4. Buttoning
If your plant encounters a stressor at the time when it should be putting on lush foliage, this can cause it to suddenly shift to head development prematurely.
5. Head Splitting
An ideal head is a compact group of florets with tight curds, whereas one that is stressed in its growing environment may split into separate sections.
6. Leaf Tipburn
Leaf tipburn is a condition that starts with the leaves and may progress to head damage.
Growing Cauliflower at Home
Regardless of the color of the head, cauliflower prefers growing in the cool temperatures of late spring and fall. Cold hardy and frost tolerant, the most flavorful cauliflower heads grow in temperatures between 50 and 70 degrees Fahrenheit, notes University of Minnesota Extension.
Blanching White Cauliflower
The edible head of cauliflower is called the "curd." A cauliflower head is the flowering stalk of the plant, which is harvested and eaten before the flowers bloom. Unless they are blanched, white cauliflower heads will turn an off color due to the process of photosynthesis in the curds.
Purple, Orange and Green Cauliflower
Over the past several years, gardens and farm stands have become more colorful with the addition of purple, orange and green varieties of cauliflower. Easier to grow because they do not require blanching, colored cauliflower is grown and eaten like white cauliflower.
1. Alternaria Leaf Spot
With about 50 species in total in the Alternaria genus, several types, including A. solani and A. brassicicola, can cause leaf spot.
2. Bacterial Soft Rot
Bacterial soft rot is caused by several types of virulent bacteria, including Pectobacterium carotovorum.
3. Blackleg
Blackleg is caused by the fungus Leptosphaeria maculans, aka Phoma lingam, that produces fruiting bodies called pycnidia and pseudothecia.
4. Black Rot
Black rot is caused by Xanthomonas campestris, a bacterium that likes to feed on susceptible plants when the weather is damp and temperatures are above 77°F.
5. Cauliflower Mosaic Virus
Cauliflower mosaic virus (CaMV) is a viral disease transmitted by aphids.
6. Clubroot
Clubroot is caused by a fungus, Plasmodiophora brassica, that lives in the soil, favoring ground temperatures of 73 to 79°F, wet conditions, and acidic soil for activation.
7. Damping Off
Damping off is caused by various species of Rhizoctonia fungi and Pythium, a parasitic water mold called oomycete.
