Does this look like hop latent virus? Plants are in soil and fed with Mills and tap water, light is CMH and MH. It appears in different areas of the room.
There not from the US. The growing tips seem to go a goldie color and the lower ones seem to die off. I have never seen anything like it. When removing tops the stem seems to develop this fuzzy stuff, as seen in one of the pictures.
Looks like some sort of mould or fungus ecspecially if you're saying it's fuzzy ..... and the browning is another sign of summit wrong plants should all be healthy and green no brown
