Aya Aya Ayahuasca

First week of flowering and the first hair are appearing. Man, it's about time. I got an interesting plant, a couple of heads are very bushy and the stems are flat, as though two stems were merged together. Only 2 branches emerging from the same node have this, could it be that the stem cells at that particular node became tetraploid?? I hope it leads to bigger flowers! Out of the three plants, one has a potassium deficiency. Older leaves are burnt and the leaves are generally smaller than on the other plants. I'm going to start adjusting pH, I hope lime juice is good enough. Weather is cooling fast and they spent a night at 13 degrees. Time to turn on the heater a little.
