11/5 - Took photos before/after pruning to open canopy. Dry, so gave each plant 1 liter pH corrected water with 2 Tbsp Big Bloom and 1 tsp. Tiger Bloom. Bloom started; flipped light to bloom (red/blue). PPFD 1400. Temp at soil 23 C RH 66%. Light above canopy 28 CM. Removed LST.
10/29 - Mixed 4 liters pH corrected water with 4 Tbsp Big Bloom and 1 tsp Tiger Bloom and gave each plant about 1.5 liters. Pruned to open canopy. PPFD 1,000. Temp at soil level 26 C, RH 51%. Light 25 CM above canopy.
