Black spots on leaves
Black spots present on some fan leaves. During ~3rd month right now. Watering with HESI in Coco Coir, PH ~6 every time, 1/2 runoff water. For about 2 weeks prior to this, I also added very small amount of kelp powder. Soil seems fine.

To my outdoor growing gurus.. How do I schedule a regular nute feed????
doing an outdoor grow and dealing with a consistent rain schedule every couple of days. Can i supplement a feed and give more water (think that's a bad idea), or do I wait until the girls are thirsty again to give nutes? Possible too much rain stunting growth?

ma plante jaunie
Je voudrais être sure. Feuilles jaunies branche rougies c'est le manque de soufre. Et cela et due généralement au ph de l'eau. Mais si c'est ca ? Pourquoi cela se voit toujours en fin de vie de la plante et pas avant ? Mon eau et prise dans une cuve d'eau de pluie.

PH-Problems in Soil
Before repotting, the pH value in the soil has always fallen to below 5.5. The plants always have an iron deficiency. I then repotted the plants and that worked well for 14 days. Now they are showing PH deficits again. The soil has PH 5,4 -4,8. What could be the reason?

Weed doctors to the rescue
Day 44, fb auto, my happy girl developed those dark spots at the top... Is this a Calmag deficiency? Although I'm giving her calmag every feeding. I think there are also first burnt tips. I'm about to water her tonight, what should or should not give her? Thanks for your inputs🙏
