Stop watering so much whenever my small plants stunt I starve them I believe yours are flooded and your roots can't breathe try letting the soil completely dry out don't worry your plant will be fine you will know if you have gone to far. Wait until that pot is as light as air and the soil extremely dry. Then just water around the plant probably 10ml or less also hold off on all the nutes they are hella burnt they will grab what the need to grow from the soil. Remember less love during this stage means happier plants
