Did some maintenance and changed out my res this week. Plants took off this week got a few issues though. First one is almost all the plants have a little bit of green mold growing on the top part of the rockwool, the area explosed to light guess thats why they make those little white covers. Going to do a search on here to see what people recommend after this update. Second issue is this NLxBB runt, this little guy has been giving me issues from the start and because of that has had some serious stunt in growth. So, I'm going to put it to death later this week which works out cause my drip system can only support 8 plants and the baby purple bag weed needs a dripper. Lastly I topped all the plants for my first time ever this week how good of a job did i do?
