My tomatoes were transplanted outside 5 weeks ago and some of the leaves look diseased. Has anyone seen this before??
Environmental stress from temporary water shortage.
Perhaps extra bright days; or windy; or too little soil moisture; or even too much soil moisture which damaged roots.
When it comes to soil moisture, put a trowel in the soil to assay its status.
Jean is that new mulch at the base of the plant? dont feed the tomatoes until it is established good,It looks like it might have had to much fertilizer
