Hello, can someone please help me identify which nutrient deficiency I have in my hydroponic system? My leaves are turning yellow. I think it might be iron or nitrogen, but I am not sure.

Finally finished my DIY hydroponics setup. It’s two systems in one: an AutoPot system and an NFT system, both cycling to the same big reservoir. I built a custom dosing system that is fully adjustable with auto mixing and PPM control. The pumps run on a timer and the whole setup is coded by me in Home Assistant. I 3D printed most parts and I have the files if anyone is interested. The spinach is still going strong after almost a year. I’m also growing tomatoes, strawberries, and asparagus.

Hello everyone! I wanted to share my hydroponic system setup with the community. I currently have three towers and one DIY system. The towers are a bit hit or miss — sometimes they work well, and other times, not so much. I’ve had some trouble with root rot, especially in the towers. But my DIY system has been the best by far! I've never had any issues with it, and the plants grow nicely and stay healthy. My tomato plant grew to 3 meters tall and lasted for six months! I’m really glad to be here and excited to keep learning from everyone. Looking forward to picking up some new tips and sharing more of my journey!
