Flipped the lights to 12/12 about 3 days ago, and boy has she sprung to life! I've also avoided adding nutrients for the last few weeks while some of the plant started showing signs of holding to much nitrogen. The Happy Frog seems to be feeding this plant just fine on its own, even after 8 weeks. It definitely improved after a couple deep waterings flushed the soil a bit. I'll watch for her changing demands as flowering hits full swing.
*This is a free included seed from Herbie's Seeds, and my first attempt at a photoperiod-flowering plant. This is my second EVER grow, after the first round (all autoflowers) was stunted from rookie mistakes (over watered early, poor substrate, uncontrolled temps) and flowered too small. Hoping to get a bigger yield from the full-season plant and improved grow methods!
