Mangos in Distress

Hello, and good day to all. I started growing these mangoes guys and gals around April of 2022. They're not doing so well. Started to notice this a few months after when ants got into them. I took off the half cut oranges I left in the pot. Pour boiled banana water in them and took the orange slices out. Ants never came back. Put boiled borax and decent pasta water in them. Store bought fertilizer and citrus food in as well. Water them with distilled water and spring (sometimes). I switched the soil for one of the pots but they're still ill. Uhhh, making compost but It's too sandy so imma start all over with that. Should I start over with my mangoes? Can't really find a place around here to donate. Just another month or two till new mangoes fall from my tree around Miami. Thank you for reading.

Hey Joe! Welcome to Permies!

First question; What are those red woodchips around the base of your plant?… I’m assuming they were dyed red and purchased as such?..

Second: is this what the leaves looked like after the ants or after the supplementation you gave to the plants?

It kind of looks to be a bacterial infection which I’m sorry to say I don’t think is treatable…

If it is; it could be from the roots being too wet in stagnant water for long bouts or too much overall humidity…

I hope your next run with mango trees goes better 🤞

Yes. Dyed at purchase. Dang it. Okay, no colored chips. I thought that was strange for the color.
A little while after the ants. I've given the supplements and fertilizer like twice. Around the fall and recently when it was getting bad.
Alright, bacteria. So Remove these from the others and focus on the sick. I ain't giving up on them.
It hasn't been raining as much as it was last year. So, I guess water every three/four days? This is why potting plants is just ridiculously hard from what I hear. The pots have holes in them on the side and bottom.
I gave one of my neighbors one and it's doing fine. I'll swing by today and ask him how he does it. He seems to have a green thumb.
Tyvm for your help, Chris. I'm going to look up that bacteria one and try my best. They're still sprouting leaves. They're not giving up and so won't I.
Have a good weekend.  

Hello and hi. Took a while to respond, my apologies.
I didn't give up on them. I talked to a few older folks, fam and coworkers.
They recommended using dish soap and vinegar mix with water to spray the leafs with.
1. I took the plant out.
2. Rinsed the roots.
3. Sprayed each and every leaf.
4. Rinsed the leafs.
5. Cleaned the pots with soap water and vinegar then rinse.
6. Refill pots with soil and put back plant.

The spots on the leafs stopped immediately and have not returned on any of the plants. Now they're growing well, happy and green.

FYI if you have something similar and want to try new things out.
