Gelbe Verfärbungen der Blätter

High squirtle, You give way tooooo much nutrients!!! You need to flush the nutrients out of the soil. I will explain you how to do. You can do this flushing by slowly pour water pH 6.2 onto the top of the soil, allowing it to drain freely from the bottom of the pot. Pour slowly, so the water doesn't overflow from the top of the pot. Use approximately four times the pot's volume in water to flush the soil. For example, use 1 gallon of water for a 1 quart pot. After the flushing you need to let the soil (almost) dry out completely. When you did this you can give water with nutrients again but please only give 50% of what you gave before that should be more then enough already! Happy Growing! 😋
