leaves turning yellow

[Don Perry]

I have a tray of purple top turnips started on the back windowed sun porch. Started them under grow lights. After the weather warmed up a little, (we had two weeks of -10 degree weather). I moved them out to my green house and tending to them daily. The leaves are starting to turn yellow. My intent is to plant in these raised boxes.
what is this a sign of and how to cure it.?

Yellow leaf green veins usually means iron or zinc deficiency. I would use some Iron Chelate

 

[Don Perry]

Thanks for your advise, Chuck. I'll look into that Iron Chelate.

Last year I had some peppers that looked exactly the same. I did the chelate and within a week I could see a vast difference. That is the same plant a week apart.

Looks great! Sometimes I wonder what I would do without people to keep an eye on me. Thanks. Where is Tarpley? I'm from Ft Worth. Retired to rural Byng, Ok.

All Tarpley is is a zip code. It's about 75 miles NW of San Antonio. I was stationed at Carlswell AFB for a while in the early 70's

Went to Lowes and picked up some 'Ironite Plus' and tomato food. I have plenty of seasoned cow manure. aged about 5 years. going to mix some of that in the raised boxes before planting my veggies.

Frabkly, I just think your growing medium has run out of nutrients, and it's time to re-pot.

 

[Don Perry]

I have doubts about the starting medium , also. Next time , I am going to start with fresh potting soil.
I filled my boxed beds with top soil. On the top I added aged cow manure from the garden supply. I have ironite and tomato food that I need to dissolve in water and spray as a general fertilizer. Growing cabbages , broccoli, Tomatoes and purple onions in the box beds. I hope I didn't make a mistake on the top soil.

Could be too much of the cow manure. Best to blend it into the potting soil mix in a wheelbarrow or such prior to potting them up. Personally I would have direct sown those.

I made the same mistake with chicken manure last year. I think it was not aged enough and the first crop planted in that area, black eyed peas, all were small and had yellow leaves. That was in the spring. Planted them again in the same spot in the fall and they did quite well and no yellow leaves.

Because of the extremely efficient digestive systems of cattle, their manure doesn't stay "hot" as long as some other manures.
If it was aged, then broadcasting it should be fine.
I've done that often enough without issue.
