First time growing cauliflower so Im not sure whats normal but i'm pretty sure these plants are not since this condition showed up overnight. I'm showing multiple symptoms. Young leaves are yellow between the veins. On one plant the oldest leaf is turning orange and on the other the older leaves are yellowing with spots of brown coloration. The system has not completed cycling yet. Im currently measuring high ph 8.0 and high nitrites 5.0 with low ammonia .25 and low nitrates 5.0. Just the other day I added iron and maxicrop for my kale which was showing signs of Iron lockout. Attachment: 100_1618.JPG Attachment: 100_1619.JPG Attachment: 100_1620.JPG

Have you added seaweed tonic? Looks like multiple deficiency - marbling on older leaves could be magnesium. Is it the right time of year in your area to grow caulis? |

I've added Maxicrop which is America's version of seasol seaweed extract. Cauliflower is a cold weather crop and while still technically winter, temps in California have been unseasonably warm. 70+ F which is low 20's in C. water temperature I suppose adding a little more maxi crop won't hurt. I could even spray it directly on the problem plants. |
