Everything is fine so far.
The OG and the Duckling are both starting to grow and looking healthy. At least as far as I can tell. The OG is 9cm in Height and the Duckling comes to 6cm.
The other 2 Plants are about to be harvested, so that i got a little bit more space and can adjust the Sanlight better.
Feel free to ask Questions and/or give some advice. I´m happy for every Input I can get.
I´m wondering, if I should use CalMac for Prevention, as I had Problems with my first Autoflower grow. So my Question would be if, and when I should start using BioBizz Calmac?
When to start depends on what medium and other nutrients you're using and what they have in them.
I use GH CALiMAGic at 5 ml/gal throughout the grow starting around week 4-6.
That's synthetic calmag though and for the soil I grow in, organic like BioBizz is going to be dosed a little differently.
But yes, I would start using CalMag in your grows.
