Purplematic / Hulkberry Auto balcony grow

i grow her a little wrong so i cant blame her for everything. put her out in too cold temperatures in the night time when she she was too small and needed the growth. also my light situation on the balcony is not the top of the peak. i got a large tree sucking up all the sunlight around 3-6pm wich does not work in the favour of the plant. also i transplant them to late i think, next year i go straight into the end pots and see how that goes. this plant got mildew on 2 days in the grow so might be not the best in therms of restistance
