Hi all ima few days away from harvest, and i have a problem. it all started when the leaf tips on the fan leaves where turning yellow and a little brown. and since i started flushing it has been getting worse and worse. even the bud leaves are turning yellow/browning up looks as if they have been burnt. this has to be a deficancy right? but i have only fertalized a few times during its life, flushing about 2 weeks ago. This is the only plant that is like it. its in a pot thats not a perfect size for it but its too late to transplant it. i think? any ideas of what i could do?
