This post has multiple questions inside that I really need help with identifying what's wrong with the plants and should I remove them, if so, which ones.
I'm also curious if any of those issues could transmit to tomatoes, figs, bananas and cucumbers in particular.
Location: Memphis/TN, grow-zone: 7-b, weather: inhabitable/uphill battle.
I have 2 sets of hydroponic peppers outside in the patio with a couple pot planted peppers. I know the diseases aren't from the seeds since the peppers inside are doing just fine but sadly I only have 2 plants inside the tent.
One disease manifests with making the entire leave to lose color and turn into a weird mixture of brown & yellow with small green specs. Here are the pictures of those:
When the disease is advancing:
And it eventually killed one of the small plants as such:
Question is Should I remove these or I could apply some sort of fungicide / hydrogen peroxide? Would there be a possible way to save the ones that still have green set of leaves? If so, do I need to remove all or just removing the obviously infected ones and treating the rest with whatever solution available out there is fine?
Other disease is I'm assuming mild mottle, I'm attaching the picture just to confirm if I'm right or not (this is also a hydroponic plant that I moved to different spot to prevent contact with ghost peppers)
Question #2 is: Is this mild mottle and if so, should I discard this or there's a way to save it?
Following are the same species of peppers with the one above.
Question #3 is: does the following plant seem to have mild mottle? Do I need to remove these? Is there a way to save this?
And finally I have the mad hatter, I thought it had some sort of fungus when the leaves started to have yellow dots and I applied copper/seranade mix with the same ratio I apply to tomatoes. It seems to have made the plant worse and now the disease seems to have spread into much more leaves than it was.
Question #4 is:How can I identify what this is and if it's bacterial, viral or fungal?
Sorry for asking this many questions in one post but I thought it may be relevant to each-other, particularly if I need to remove all these plants... Hopefully I could get some sort of an answer from here before I cause damage to the garden.
