Another week of overall slow recovery. Before I went away for a week I've exchanged the water again, cleaned both res' and gave the plant fresh water for 2 days and than added just a quarter of the normal feed. I've also put 4cm of styrofoam under the reservoirs to raise water temperature. After a week of me being abscent the plant developed and is the second biggest even if it's at least half the size of Hulkberry. From what I read looking at the plant, it needs a bit more nutrients which I gave it and also stabilized PH to a perfect 5.8 with no issues comparing to last week. Things are starting to look better. Hopefully I've got most of the issues under control now. I've also raised the night temperature a bit which will do good for all the plants :) I'm happy with the result because I was expecting half of the plants to be dead after my holiday. :)
