What kind of infestation is that? What has caused it?

It's in fact caused by a calcium deficiency, This may result from low
calcium levels or high amounts of competitive cations in the soil,
excessive soil moisture fluctuations which reduce uptake and movement of
calcium into the plant, or rapid, vegetative growth due to excessive
nitrogen fertilization.




I feed them with Tomorite.. wouldn't that help?
