Yes, organic I am fertilizing with a general 5-5-5 fertilizer. I just give a little bit every other week. It's organic stuff from Gardners Supply Co. and says it won't burn. But I don't know if thats sufficient or not? It may not be if I'm overwatering. Anney, the plants are a good 3 to 4 inches tall. I have about 4 to 5 true leaves on each of the plants and the 2 to 3 remaining leaves look green and healthy. But the bottom 2 leaves look wilted and yellow. My Garden Oasis cucumber (1 plant) looks worse than my Diva Cucumbers (2 plants). But all of them have the same problem - they look good except those bottom two leaves. I'm also using Gardner's Supply seed starting trays. They are the foam trays with the wicking mat on the bottom. But I got them into cowpots within a week or two after they sprouted. I admit, I probably started these seedlings too early. I didn't realize that some of these plants would get so big so early. Already made of a note of this for next year. :-) I try and stick my finger in the pots to see if it's moist, but I do it more on the outside of the cowpot instead of the center. After your post, I attempted to stick my finger in the bottom through the tiny hole and it seemed somewhat moist to me. It's a bit deceiving as the top of the soil is very dry. So I think it's fair to assume I may have overwatered them. I did kinda pull one out of the cowpot to see if it's root-bound and it does not appear to be the case just yet. Do you think I should snip off the yellowing leaves or will that not make a difference at this point? I can easily go ahead and start some new seedlings to cover myself. It sounds like you think it will not make it another 3 weeks until it can go outside? Thank you both for your input! Sue

It looks like there are several different things going on but one of them looks like "Yellow Vein Disease". That one thing kind of overrides all other issues. Sorry Here is a link that might be useful: Remedy for Yellow Vein Disease in Vegetable Plants

I am watering every other day.Since few days I am spraying to soak entire vine area so that there is enough moisture between all branches of vine and ground and above.I hope this will reduce some stress due to dryness in these hot days and help transpiration.I am waiting to see if the new leaves are free from yellowing.

Hey there. Those UT mountains in the background are killing me! Don't get a view like that in NC, but it's lush and green here. Usually yellowing is due to nitrogen deficiency or overwatering. Since it seems like you had plenty of nitrogen, I'm going to guess overwatering as well. Also plants dropping flowers can be due to overheating, and I heard it got pretty hot in your area this year. My parents live in UT, and they only water 2 to 3 times a week during ave summer weather -- more when it's over 95. I have the overwatering disease so I finally bought a cheap moisture meter at Lowes and my garden is doing great, whereas before everything was yellow. Best of luck to you!
