What do you all got for this deficiency .. I thought I was hitting all notes but I guess that is an older larger fan just before I got the emerald harvest... anyone got a clue what the white dots with slight burnt tip is.. it's not pests and it's on older mid to lower level fans. All the plants have a touch of it around the same level in growth ..I'm stumped but it's corrected thabkfully just wondering what it is or was because all new growth is lush and emerald
