Is this considered overcrowding I want to also add around 30 cherrys shrimps.
Added a meanwell eln-60-48d also made a diy black acrylic enclosure for the driver waiting for the 3 Digital Blue led Amp Panel Ampmeter and the 10v adapter to finish it off. Everything is growing but some of the stem plants the middle is starting to turn dark and dieing what can cause this?
