Some of my leaves on all of my plants in my garden are yellow. On my cucumber plants it is more of the tips all around the leaves. On my tomato plants it is more around the bottom of the plant the leaves are a little yellow. And the same thing with my pepper plants. HELP
This is an indicator that the plants are underwatered. You should increase water to the plants and this should help.
It is also possible that they have received too much water, but this would only happen if they were growing in soil so saturated that it is basically standing water. Some areas have received large amounts of rain, so this could be a possibility. If it was too much water, the symptoms will fade once normal rainfall returns.
My cucumber plants are beautiful--broad dark green leaves and many inch to inch and a quarter cucumbers on each plant. Some of the small cucumbers are turning yellow on the ends and not growing. Any suggestions?

Our cucumbers began to get bitter on the ends about a week ago. Now they are turning white while on the vine, even though they are picking size. Is there anything we can do? What is causing them to turn white, and are they still OK to eat? No, they are not of a white variety. Thank you for your help and time.
Plant stress is a common cause of bitterness. Too much water or high heat are common culprits. Once the fruit begind to turn bitter, there's not much you can do. Future fruit will also be bitter. The season is still young and you have time to plants new ones.
I planted my first cucumber plant about 6 weeks ago. I have had many yellow blossoms, but so far only one cucumber, about 5 inches long now and it is curled. Should I have more mature cucumbers than just the one, in this amount of growth? Just learning the process.
You may have a pollination issue. Squash and cucumbers are pollinated in the same way, so these articles will help you:
We planted Japanese cucumbers a couple of weeks ago. The vines appear to be robust; however, some cucumbers at the earliest stage of development are turning yellow. Is there a problem we are not aware of?
This is caused by a pollination problem. You may need to hand pollinate if pollinators are having problems getting to your plants. This can be done swirling a small paintbrush inside a male flower and then swirling the brush inside a female flower. These articles will help with attracting more pollinators to your yard:
Each year I have trouble with a disease affecting my cucumbers. Just about the time they start to fruit, the leaves begin to yellow and holes form like they were burnt by a cigarette. The plants wither, lose their leaves, and eventually die. Is there a fungicide that will prevent this? I have relocated the garden but still have problems.
Gummy stem blight commonly affects cucumbers, as well as many other crops. Gummy stem blight can appear anytime during the season, but most damage occurs late in the season after the fruit is set. Warm, wet conditions favor the development and spread of the disease.
This fungus can be controlled with fungicides if caught early enough. To prevent re-occurrence, you should practice crop rotation. Do not plant the cukes in the same location. Also make sure that all plant debris from affected plants is removed and destroyed.
I want to know what to do with cucumbers that taste bitter.
You may want to toss them. If they are large, then they are probably over mature. I would try picking them a little earlier. Some varieties may look white instead of yellow when over mature.
