Yellowing and ends of leaves dead
I have water catches under all my plants and rocks in the bottom. They are growing at an amazing rate but dont know why some leaves turn yellow and dead looking at the ends. I have to trim them constantly. Any help would be appreciated
This could be a problem of inconsistent watering, salt or fertilizer buildup, or toxins in the soil. If the same water stands under the plant's container so that the soil can reabsorb it through the drainage holes, salts can build up in the soil, and the soil can stay excessively moist. This could cause the symptoms you see.
You can get rid of any salts or toxins by flushing the soil (watering until the water runs out the drainage holes for several minutes), and by making sure the water is allowed to drain (or is removed from the tray beneath the plants) after each watering session.
