Overwatering problems

I would recommend Transplanting them to larger pots. 5 gallons should do in fabric....no need for stones. Get something that has more porosity like promix HP and then there is no need for stones on the bottom. Hope this helps

i mean you can try a method that worked for me in the past, but was super challenging. I got a huge tote, like 40 to 60 gallons. added dechlorinated water, then slowly and super carefully put the entire pot (they were small like yours, maybe 3 or 4 gallon pots) and softly massage the root zone. Just be careful. the water will get messy and draining that down your bathtub would be bad and clog all kinds of pipes, so be sure to dump water outside. At this point I was able to clean the root zone, inspect for root rot, cut away any rot, then place back in a much more aerated pot like an Air Pot or Fabric Pot with lots of drainage. And while you are in the root zone add some DynoMyco! the best on the market for real! Fill half of pot with new aerated soil mix and mycos, then carefully add plant roots. filling as necessary. This helped me tremendously and saved my plants. now I will say you will be going through transplant shock not matter how delicate you are. Just add some Lactobacillus (LABS) to your next watering, they are beneficial bacteria that can live aerobically or anaerobically. Meaning that the Lactobacillus will establish in your soil and fight the bad bacteria and disease, even if your soil goes anaerobic. Strongest microbes in the universe right there! To make LABS: rice in water, strain water. place rice water (now slightly cloudy) in a glass jar (fill to 1/4 full of rice water), cover with paper towel or any clean clothe, then use rubber band or hair tie to prevent anything from getting in the glass jar. Let sit in dark location near your grow for 2 to 3 days. Now you have collected all bacteria in your local area, we submerge them in milk. Yes whole milk. So add whole milk in that same glass jar that was 1/4 full of rice water, and fill with whole milk until 2/3 full. Repeat process of covering with paper towel and rubber band. After about 4 to 7 days, (shorter in hot climate, longer in cold climates), there will be a yellow/cloudy liquid at the bottom and a cheese curd forming at the top. Once the liquid has cleared up slightly and the cheese curd on top is more firm. Then strain the liquid, THIS IS LOCALLY GROWN AND HARVESTED LABS, or Lactobacillus. Highly beneficial, use in root zone, use in foliar sprays in veg. discontinue use in late flowering if applying as a foliar spray. Remember that LABs can live in anaerobic conditions, meaning they will prevent root rot going forward. This can be used in emergencies as aid workers as well as a preventative. LABS will also outcompete Powdery Mildew as well as other diseases. Check out Chris Trump's Tutorial on Youtube for more details on how to make LABS, also feel free to reach out, will gladly walk you through the process.

well it's not something you can fix midstream. simply fix irrigation habits. Stop choosing 100-150ml ... it takes what it requires, you learn in hindsight what it is. water until entire thing is saturated... wait for top 1" to dry before repeating. simple as that. if they droop for a bit after irrigation, that's not optimal but not much you can do about it now. in future use closer to a 50/50 mix with perlite or similar. the clay balls at bottom is a nice thing too, as that helps avoid subsrate sitting i a puddle of water at bottom. REgardless, follow that wet-dry cycle as described. even in this context it's better than trying to micromanage it with small volmes of water... all you'll do is promote superficial roots and increase risk of issues in your root zone. You don't pick the volume to give... the amount it has dired and the water capacity of the substrate determined how much water should be given each irrigation. don't let it sit in its runoff even with teh clay pebble layer at bottom. get rid of any runoff. a raised pot that allows water to drip below is best. they sell cheap little 2 $ risers 12-15" wide... some are overpriced. can get created with such stuff.. certain kitchen products can work fine for raising a pot too. Anyway, one less thing to worry about this way. can let runoff drip off or dry i guess, but still better to get rid of it to prevent unwnanted microbial growth.
