As a new gardener with just a couple of raised beds, I was really hoping someone could tell me what was happening with some of my plants (especially my tomatoes and cucumbers.) The weather has been a little tricky here in NC, brutally hot with periods of thunderstorms and hard rain, so I'm not sure if it's related to that, my watering/fertilizing schedule (or lack thereof) or what. Any insight or tips would be appreciated!
The tomatoes are yellowing seemingly all over , although I have noticed some green offshoots and they are still producing (though not as prolifically) and I have noticed some dropped/cracked fruit as well as fruit not growing to maturity (ripenif when very small.) As for the cucumbers it seems as if the pickling plants have all but died back and aren't producing cucumbers (aside from a very larger specimens I have since plucked that began to go bad before fully developing.) The Mexican Sour Gherkins are doing seemingly well on the backside of the A-frame, but seem to be thinning and yellowing on the front side, I have also noticed them dropping a fair amount of fruit which may or may not yet be ripe (it's my first time growing cucumbers and I'm not especially familiar with this variety and how large they normally get, I just know they aren't supposed to get as large as standard varieties.)
hau Jenna, that is a sign of low manganese, and or magnesium. The fruits are also showing signs of low manganese.
Try some Epsom salts sprinkled around each of the plants and water it in.
About 1/4 cup per plant, after watering, watch them for around a week to see if the leaves don't look better.
If they don't then you will want to get a multi mineral regimen going.
Mineral defects are the usual reason you get yellow leaves like those.
Calcium, manganese and magnesium are the big three that are usually low in soil just about everywhere.
