Hey everyone, one of my Strawberry Banana auto plants has started showing rust spots on the upper leaves. I’m using super soil and none of the other plants have this issue. I prepared all the soil in one batch and split it evenly into the pots. I’d love to hear thoughts from the experienced growers here. Thanks in advance and happy harvests!

Looks like a Ca or K issue that plant may be sensitive to N causing a lockout issue

Looks like Ca and or K? Too much N can cause this.

It looks like you are watering wrong?  
What you need to learn about watering will come with practice. Here are the basic rules: Never let the soil dry out. Soil and or coco can become hydrophobic if allowed to dry. This means it repels water. This in turn will create dry pockets in the soil and the roots and microbes will die there. If your soil - coco have accidentally dried out use a surfactant to help re-wet it. I like yucca powder. Don’t let soil remain soggy by watering too much too often. Root rot, damping off, molds, fungus gnats and other problems start in soggy soil. When you do water **water the entire pot**. How to learn when to water starts before you plant the seed. Fill your container with fresh soil/coco and weigh it (heft it) this is the lightest weight and consider it a dry pot. Now slowly water until the soil/coco will no longer absorb the water and run-off begins; weigh the pot (heft it) this is the maximum water, the wettest the pot can get. The difference between wettest and driest is the maximum water weight, for ease of explanation lets just say the water weighs 20 pounds. When the pot loses 10 pounds **(half of the water weight)** it is time to water again. Slowly wet **ALL** of the soil until run-off begins. There is an art to watering. Make sure there is an air gap under your pot, you do not want runoff to be reabsorbed and if no air then anaerobic microbes can grow. This is a cause of root rot. Coco can be fertigate many times a day if you want to continually present fresh balanced nutrients to the roots. Begin fertigation 2 hours after lights on and end it 2 hours before lights out.

Good luck​🍀🍀🍀
