I have a crisis! We had visitors last week, so I wasn't paying as close attention to my girls as I had been & somehow in the space of 7 days they've gotten sick :(
I suspect leaf septoria or a calcium deficiency (see photos - argh!). I'm in a bit of a spin and need some good advice now.
I'm two weeks away from harvest, and I'm not sure what the best course of action is. The smell in the tent has changed in the past 24 hours from thickly weedish to a little sharpish sour. This week was meant to be last week of nutrients, then the flush the following week, then harvest. The top leaves are definitely affected.
So that's where I'm at. All advice appreciated!
EDIT: After doing a total deep dive, I'm confident it is a calcium deficiency and not septoria - phew! From what I've read, this is a common problem when using BioBizz nutrients and rainwater. I don't have a cal-mag nutrient in my arsenal here and it could take up to a week to get my hands on some. I also want to keep things organic so I'm improvising. Ground up egg shells (calcium), epsom salts (magnesium), unsulphured molasses (more calcium, magnesium, iron & some other good stuff) to the rescue! Unfortunately, this means my grow is no longer vegan but the chickens that are responsible for the eggshells being used are our own very happy chooks. Wish me luck!
