Q.Potted Plants
Hi, I need help with troubleshooting for 3 different plants.
Photos “garden” and “garden4” are of my cabbage plants, these were started in the pots about March 15th and they seemed to have stopped growing. The bottom leaves turn orange or purple and dye off and the stems seemed to have turned woody. I’m not sure what happened because they were going so well and then they just weren’t
“garden2” is of my radishes. I started them about 1week ago, they sprouted up nicely and strong then 2 days ago a few fell over, the next day they all fell over when I plucked this one out of the ground for further inspection it seems to be thinning in some parts of the stem– again not sure why.
Last photo “garden 3” is of my zucchini plant. This one bummed me out the most. I start it from seed it was going great, transplanted really well. I started this about March 15th. 2 days ago all the leaves start browning and shriveling up. I have NO clue why. I’m so sad about this one. Please help.
Thank you

It looks to me like fungal problems, specifically a fungal disease called damping off. This article may help:
