Cherry Bomb Auto [free grow, untrained]

Finally able to increase the light schedule to 20/4! The plant is super tiny due to 3 weeks of 12/12. Started feeding 1/2 strength BioBizz recommended schedule. Tips starting to yellow up despite being fed and soil being somewhat dry. Hmm. Let's see where this goes. Edit: Turns out it was heat stress in early stages -- I didn't account for the moisture being sucked out of the air by the diatomaceous earth I have strewn out to combat fungus gnats. I saturated the DE with water (It sizzled! Crazy stuff) to raise the RH% to ~70, and fungus gnats still die on the DE. Success!
