hey bertabud, looks like you've forgotten to update the pics so not much i can say for sure, but based on the 30.12.18 pics looks like she basically got a bit of Nitrogen deficiency and a bit of magnesium deficiency. you can tell from the yellowing between the leaves. She might even have been root bound, so you did well transplanting her. next time avoid flushing simply because it doesnt seem like much but it's actually quite stressful to the plant. Anyway i see you have floramicro, so what you want to do is take the max recommended dose for watering and add 50% to that which should be saturation levels so 6ml/L and make a foliar spray, so just that solution in a spray bottle, spray until dripping wet once a day every day for five days or until the plant is completely recovered. She'll pull through, dont give up and dont panic ! hope this helps ! 🚀
