Hi

I'm a few weeks ahead of you using very much the same system might be worth you having a read of my log as the tips I have been given would be relevant.

I intended to stick with just PH 5.8 water untill the 5th set of leaves started to show. But like days before that happened the stems went a bit red & looked like an (N) def due to the distilled water I was using.

Compared to mine your beanlings look ok for 7 days.
