Second run / Critical +

I'm testing how will she grow when I just let her be with something in the reservoir Day 9 Shes not lookin' healthy but I hope she will heal herself soon. I have few more plants in the same system and they are not showing these symptoms so not going to do anything about it. Day 12 Getting worse so I might have to add some nutes or maybe change the whole profile of them to her back to health. Foliar feeding with base nutes would be a possibility. Day 13 Today I made foliar spray with solution of calcium nitrate and solution of epsom salt combined. Lets see how she reacts. I really don't know whats wrong with her so I'm just testing what happens when I do something in these random situations. So this is just learning Day 14 Covered the hydro with black and white plastic to get more out of my system. Also changed the whole reservoir with new nutes and fresh water. This should help my girl alot. Ec 1.0 pH 5.7 Also planted two more seeds, just in case this one does not make it.
