the seedlings have once again stop growing..

Now i have really no idea what is limiting its growth. The water have been change and the nutrient concentration lowered. When can i eat my pak chois?? As im changing the water, i have notice weird stuff in the water. Black particles, leaves (not from the pak choi) and bodies of dead insects. Perhaps due to the hot weather, the insects are either hot or thirsty and decided to make a nose-dive into it. Of course, they drown. Or maybe the nutrient solution to them are something like pink dolphin to us. Full of vitamins and minerals.


Leave my Pakchois alone!!
