Bloom or Gloom

[Simon Bolivar]

For my 2 pennyworth, that's what we wiuld gave called bloom before our recent education informed us orherwise. However, unlike the white fluffy stuff, this is no problem. As our stalwart member PJ said, brush of (I keep a hog hair artists bristle brush next to my humi for this purpose). Don't brush this off or fluffy mould, near your humi's incase the spores fly about & end up affecting other sticks.

I don't think any change is necessary to your temp/ humi control but keep a regular eye on your stock, incase of further problems.
