Hello my Gorilla Glue is in its last few weeks of flower and it is just now starting to show red streaking in the main stalk and a few of the stems. Is this a normal thing to happen in the home stretch of flower? Sent from my iPhone using Grasscity Forum
having exact same issue.... cant pinpoint but i can rule out temp, humidity, and most likely phosphorous. ( my research turned up phosphorus defieciency)
Usually a phos deff or cold water temp/root temp. I get them sometimes in coco. Nothing to worry about.
