Damo's Perpetual Garden

Well after having to spend 4 days in hospital plus 2 where I wasn't well enough to feed her has made a problem worse. She was fed but I doubt properly. She has downward pointing leaf tips and purple leaf stems which she always had. The lower and mid leaves are turning yellow. It could be a fad starting but the buds are gonna have to crack on and fatten up. If anyone can think what it may be . I've cycled throu n,p,ca and mag deficiency but not sure at all. I hope to have better news. Update. I stopped the decline with calmag and with it being week 8 now I am flushing. I have harvested some tops to finish the 2nd tier blanket
