Can't identify whats ailing Sweet 100s
Hello, I planted sweet 100s from Home Depot last August and been having some issues identifying what's ailing them. As shown in the picture I cannot determine what the white fuzz is. I've done extensive Googling but the only results pertain to leaf mold or the natural white hairs on the stem and this is neither. These are container plants on 22inch plastic home depot pots sitting on the water collecting dishes (term?) in a balcony 3 stories up. Yeah, bigger container would be better but i dont have the space. I do light weekly fertilizer with the blue Miracle Grow crystals. I have a bottle of Sevin that Ive never used. I try to keep them well watered. Any ideas what it could be?
I did make the mistake initially of planting too many together on the same pot. Currently there are about 4-5 on the same pot. Will try to post another pic soon to give a better idea.
Any comments are greatly appreciated.
