So, I ran this French Macaron in living soil, with top dressings up to week six of flower. Personally, I made the grow harder than it had to be b/c I got lazy.  Didn't monitor the ph until it was too late.  B/c of I didn't, it created ph fluctuations resulting in nutrient deficiencies, which took two flushing to correct.  So, word to the wise, monitoring ph, ppm, and PPFD is critical regardless of soil medium.  I think with a more advanced grower this plant would have performed much better.  Have to have another crack at growing her.
