Mimosa Gum - A foundling seed

Hello mates, this journey started together the Amnesia's and Bruce Banner's seeds, i germinated three seeds that i don't know the provenience, foundlings' seeds. So i didn't know also whether they would be a male or a female, they sure came from a buds of a femizied plant but who remembers which one? Who knows what they'll become? 😇 Two of them germinated without problems but one of them showed some sings on the leaves like a possible fungus so, considering that in my tent i only run 4 plants togher, i take away it from the tent. I did watering with 700ml [T 22.6°C - 131 ppm - 0.26 ms/cm - pH 6.34] splitted into three pots in 2 wees then i gave at the survivor 100ml with BioEnhancer (Green House Feeding) [T 22.6°C - 167 ppm - 0.33 ms/cm - pH 6.4]. Light schedule: 1 LED 200W 100% 16Hr on / 8Hr off Water info: Base water with 4:1 ratio (demin:tap water) with 0.2g epsom salts added to balance salts on 5L. pH: 7.25 - ppm: 169 - EC: 0.3 ms/cm
