Twix Aphen Posted Thursday at 08:51 PM Share Posted Thursday at 08:51 PM Hello, what do you think it is causing the discoloration and the burn holes? It looks like the media has either run out of potash, the coco wasn't buffered and rinsed properly or the silica has kicked the pH out of range and potassium is unavailable. One or the other, those plants are showing a deficiency of K 1 Quote Link to comment Share on other sites More sharing options...
Twix Aphen Posted 19 hours ago Share Posted 19 hours ago (edited) Hi again. Your pictures have prompted me into action. Today I've used some potassium sulfate spread over the the garden and it shall be washed in with the next watering, or rains again soon if we are lucky. https://organitek.com/potassium-deficiency-in-cannabis-plants/ https://www.cannabisbusinesstimes.com/nutrition-plant-health/cannabis-plant-nutrition/article/15687380/how-much-potassium-does-cannabis-really-need Edited 19 hours ago by Twix Aphen Quote Link to comment Share on other sites More sharing options...
