Hi, Ive been reading your diry up to week 6. And the Good news the Strin you have chosen is very resiliant. Ok here comes the reality. You are feeding way to much nitrogen , starting in week2 and adding every week one fertiliser. (short version). Every Fertiliser... EVERY.... got the same Nutrients N, P, And K...... they are adding up (GO-Thrive, Calmag, Bio Marine... those got Nitrogen... . Yes calmag Tooo , only one percent but its adding up. Its a great descision that you stopped to give those amounts of fertiliser. I would recommend you to read a good helping site that explains how tu use those fertilisers. And if its organic or not chemically its alwys threee comopnets NP and K. ok enough now .
And back to your question. Your plant is looking (surprisingly) healthy, The curling under ist the result of your flushing. She is slightly overwatered. But no problem. You can start giving her Compost teas or (low dosages of P and K those are the elements she need in flower. Every blooming feritliser got it. I will link you in the comments a good sites for compost teas for flowering plants.and a general helping site
