Mimosa Gum - A foundling seed

Hello mate, first week of vegetation, i started with the transplant of this little lady. I know that i should have waited she was more grown up but i needed. The soil used for germination in the first pot was my reconditioned soil without any information about the its propriety or pH, so I was afraid this could make her feel bad. I covered the hole with 5g of Mycrotex (Biotabs) after i added the feeding at the soil, BioGrow (Green House Feeding) 40g (2g/L of soil), i Use the half dosage because the Ligth-mix of biobizz is lightly fertilized. Looking the others plants in the tent she slowed down after the transplant otherwise she looks good. Unfortunally i have some little bugs in the tent like fungus gnats or thrips so i put some traps in the vases and to prevent the attack to the plants i nebulized them only one day during the night hours with Neem's Oil and Potassium soap (10ml/L of water each). I changed the ligth schedule and i add the second Led: 2 Led 200W each dimmered at 75% I did watering twice in this week: the first time i add Bioenhancer (0.5g/L) 0.5 L of water + bioEnhancer 0.5g/L + pH-down 4 drops/L T 22.6°C - 167 ppm - 0.33 ms/cm - pH 6.4 0.5 L of water + 2 drops/L pH-down T 22.6°C - 131 ppm - 0.26 ms/cm - pH 6.34
