Brown spotting

Hey there @DazzD unfortunately I’m all out of medium and space in my tent for anything bigger than a solo cup 😕but would have done something very similar if I had the option too 👍 Happy Growing Cheers! 🌱🎄🔥

Is that a solo cup your in? first i would transplant that into a larger pot even though its in flower, Looks rootbound to me or locked out.no plant can take up essential nutrients when the root mass is so constricted and starved of oxygen. Transplant it into fresh soil, give the roots a sprinkle of mycorrhiza, lightly water, place under ya light, but to the side not directly underneath ,it doesn't need anymore stress, give it a couple of days or so to recover, let your pot dry out (pick up and check weight),then give a feed half dose, or you can make up a composte tea! ( any compost. A hand full,, molasses 1/4 teaspoon,, worm castings 1 teaspoon, and 1 teaspoon of bat guano, if you've got cal-mag 1ml of that will help. Throw all that into an old sock or cheese cloth and steep it into about 1/1.5lrt of dechlorinated tap water, if. you've got air pump and stones (great) if not stir every hour or so for 24 hrs.. Give the plant all of it don't worry about run off.im sure you will see a massive difference in 5/10 days or so.hope this helps a bit
