Grave77started grow question a year ago

Hi. What is it missing? Is it a lack of potassium and phosphorus? or rather due to weather or old age. This is an older leaf from the middle part of the plant

Your girls are lacking Phosphorous from where I'm standing. I looked at your feeding regiment. Seems to me like you have no MACRO elements. Just B-52 and some other stuff? Get yourself some 3 part grow-bloom-micro bottles and start adding a proper feed regiment. I noticed your plants are wet on the leaves and buds. I hope you aren't spraying them. If you are, stop. They don't need to be misted. You're just gonna rot out your flowers and make them vulnerable to pathogen invaders.

Fellow growers, after a few weeks of beautifull growth, I now start to get yellowing leaves which dry up and starve. I am. I am doubting between a lack of nutrification or over nutrification. I suspect the latter (biocanna nutrients and soil). Any ideas? Thanks!!

Is this more nutrient deficiency?I believe the yellowing and brown spots came from the roots starting to suck up more water than the previous weeks. Do you agree that the Durban Poison had some nutrient deficiencies?
