I Flask seeds of several species on media #723 to which add some coconut water. I did follow the book regarding preparation and sterilization of the media. I did test the media for one week and no contamination. I did seed after a week of the preparation of the media and I am noticing now that in some flask there is quite a good amount of free liquid which was not there at flasking time. Also I did notice in one flask the liquid with a milky coloration. Can any expert in the matter tell me what is join on ? The flasking already run in its 10 day. I do not notice any fungi or bacteria growth.
