Mimosa Gum - A foundling seed

Hello mates, the little one also in flowering. She is definitely the slowest of the tent, i don't know why, meaby the transplant, meaby some disease from the old soil, meaby the intensity of the led during the veg phase. Anyway i try to stimulate with the LST techinque and a bit of pruning because is little but very dense. I feeded each plant with 80g of BioBloom-Green House Feeding ( like 4g / L of soil) I changed the ligth schedule: I give at the plant 12Hr ON/ 12Hr OFF of light and i put the leds at the 100% of power Watering: 0.5 L water + 2 drops pH-down T 22°C - 131 ppm - 0.26 ms/cm - pH 6.3 1 L of water + 2 drops/L pH-down (x2) T 22°C - 131 ppm - 0.26 ms/cm - pH 6.3
