Last week of 18/6!
The plant is drinking more and more. I wasn't home one evening and missed a feeding. The plant was completely wilted already 14 hours after the usual feeding time. I gave it some water and it was thankfully back to normal when the lights came back on 6 hours later! There are some signs of deficiencies on the leaves now, though.
The plant is about 30 cm tall now. Just tall enough for me, assuming it doubles in height during flowering. 12/12 starts tomorrow!
