I've been told this is a potassium deficiency? At first I thought it was thrip damage, but then someone told me that potassium has a weird way of showing defecencies... I'm going to be feeding my plants tomorrow, top dressing with some bio live from down to earth and then a week from now I plan on using a compost tea so hopefully that'll boost the soil life so the plant stays healthy but i figure I'd come to the good ole thcfarmer page to get everyone's opinion on what it could be... the advice is much appreciated, I've only been growing for a year and a half so I'll def be on this page alot this year when I have a issue that is...
