what kind of soil did you use to repot? dose it say it contains nutes in it? how long ago did you repot them?
also you cant just say you will water every 2 days or so by 300ml, you should gauge if the pots need water or not,
give a good slow watering till you see run off make sure the soil is obsorbing the water and not just finding the easiest route out of the bottom of the pot by cultivating the first inch or so of soil as you gradually add the water, i usually water one plant a little then move on to the next an then return to the previous abit later an contine to do this till i get runoff from my pots, then once you have watered well, let the pots dry out well,(try let it go an extra day the first time plant will wilt just a little dont worry will bounce back with a good water just dont let it go too long!) cultivate the topsoil every so often this will help you to determine weather or not you need to water as well as lifting the pot every now an then to see how heavy it is,
keeping the medium damp can be dangerous an can promote root rot an eventually kill a plant if really overwatered,
these plants like to have wet dry period roots need oxigen too an if the medium is always wet it cant get any,
and if there is nutes in you soil i would just try a good watering of ph ballanced water an then when they nxt need watering do feed, feed again an then water and repeat this helps to prevent build of nutes causing burning over time
