Hi all and thanks in advance.
I have a 6 week old sweet seeds pure red cbd auto gwowing in a coco /clay balls hempy. Nutrients are kiss method GHmaxibloom currently 1.4
grams per litre. This method has always served me well.
Normally I use tap water with extra cal mag but this time I used rain water for the first few weeks.
When the spotting appeared I assumed it was a cal mag issue so reverted back to tap water with 1ml per litre cal mag.
The issue now seems to be spreading to the majority of leafs.
Any ideas guys?
