Quick one fellow growmies, what's the cause of hollow stem? I've had 2 autos do it to me recently but not my photos, just wondering if it my error or if its genetics?, cheers growmies and remember stay frosty stay green, peace and love!
There are so many people that say different things. Some say Boron deficiency some think its a carbon deficiency at some point in the grow then you have people saying it's genetics and low air movement. Then you have people who say hollow stems produce higher THC in the plants so it's honestly hard to pinpoint what actually happened during the grow.
