One of my young plants has a few dead leaves that look wilted i left it in the greenhouse in some 39 degrees weather(warmer in greenhouse) but the other plant is booming.Think its cuz it was to cold,overwater,or incorrect ph any thoughts? Sorry for bad quality got a potatoe and i couldnt use flash it was almost dead

Did anything happen when you transplanted to that pot

But I’d say ya she just needs a little love, cool spot and let the soil get dry befor ya water again that’s what I do,always address environment issues first before going to deep into more often then not that what it is

If it was me I would transplant into a bigger pot and let the soil pull excess water away from it’s roots.if it was ph both plants would be effected.the others growth looks healthy that’s why I would transplant but this is only a opinion just trying to help
