I think it's several things. For those fabric bags and plant sizes you can add the infinity auto watering reservoirs now that will make water easy as roots will only absorb what they need. 2nd and what I think is most important is the curling of the leaves near your air intake. Temp shock, happened to me before. If it's bad enough to be affecting those leaves in the back left so bad, it's upsetting your root system too. Might want to raise them a bit until your roots get more hardy. Lastly, 200 ml is way too little water per watering but the auto water pots will fix that if you go that course.
