If my tomato plant has blue curled leaves...what does it mean?

Question

My tomato plant has blue crunchy curled leaves. Does it mean im over watering it or im not watering it enuf?

Thanks for all the help from u ppls.

Answer 1

Copper deficiency:

Stunted root and shoot growth, blue-green curled, flabby leaves, few or no flowers. Manure is an easy cure; copper salts can be used with great caution (in too high a quantity, they can kill plants.) Bordeaux mixture fungicide (a mixture of copper sulfate, lime, and water) applied at fungicidal rates will work.

Answer 2

Mine have been in exactly same state as yours - it is, in my case, because all nutrients have been lost over the years in the greenhouse.

Now I will dispose of current soil, replace with plenty of compost & horse manure & leave to over-winter.

Next spring I will be adding chicken pellets prior to planting.

Best wishes.
