I have about 7 Tomato plants of 3 different varieties. About 4 days ago I noticed the new leaves at the top are all very yellow. No spotting, no green, no wilting. All the other older leaves are dark green. What could be the problem? I use an organic fertilizer and have only fed them once. We did have about 2 inches of rain over a two day period here. Let me know what you think. John
I don't really know, may need a little iron. With all that rain leaching out the nutritents you may need to reapply.
What sort of pot are they in or are they in the ground? Firstly id say maske sure they have some drainage, then apply a feed. Something suited to toms (if not specifically for tomatoes). Remember to water in the mornings (when you do) and before the sun hits them fully. You should see them recover, theyre probably just a little down after the heavy rains.
