Week 14 or, day 98 if you prefer. I should have had to have harvested these by now as we were expecting guests for two weeks, arriving today. Not often I am pleased to NOT see family but I am because I would have to had chopped these last week in order to get them processed and everything packed away. It would have been too early, as you can see from the pics. So, what's next for the girls? Flushing, I think, although every time I think about watering only, I end up thinking "one more feed will be fine" but really, as you can see from some of the pics, at least a full week, maybe 10 days of flushing, then chop, should work out fine for harvest on or around day 105. There's some leaf discolouration occurring on one of the girls, as per pic 3 or 4. Given the veins are green and it's leaf yellowing between, it looks a bit like a Mg deficiency so I have added some Epsom Salts to plain water and given all 3 girls a bit of a boost. We'll see if that helps over the next few days but that said, we're almost done now so I am not going to worry about a minor deficiency at a week before chop. Thanks for reading/looking!
