This plant used to be ginormous however all of the leaves started turning yellow around the edges. At that point I thought it was too big and it needed a repot which I did then that turned into a different mess. Now, the leaves are starting to turn yellow again and there are negative zero signs of pests. I water ALL of my plants using using Superthrive Foliage Pro which does contain Calcium and Magnesium, however it has been suggested to added calmag to it. Im scared that would be too much fertilizer. Does anyone have experience qith this? The plant is in pon which sits in a water reservoir. Ambient Humidity sits around 50%-70% with dips down here and there. I check regularly for pests as well as spraying them with 70% rubbing alcohol once per month for prevention. Any thoughts or suggestions are greatly appreciated
