Tomato yellow leaves
What is causing some yellow leaves on these tomatoes? 5-10-10 was used when planting and when yellowing started soluble acid fertilizer was used once. Plant has been dusted with sevin/copper dust and later sprayed with pyrethrin/piperonyl butoxide spray. Nearby parking area was sprayed with Roundup EC but I don't think it drifted. Thank you.

Hi- we can see what appears to be minor feeding injury, probably flea beetles. The color breaking on new foliage does indicate possible glyphosate injury:
Hopefully, it was a small amount of drift and they will grow out of it.
