Any ideas on the photos above. It's the plant thats flowering that has this prob. I corrected the PH to about 6.6 and ferted using Bio-bloom 2ml per liter I've also added 1/10th of a teaspoon of epsom salts to the liter of water. the prob was there before I Mg'd it so I don't think it will be salt build up. I'm wondering if it's a micro nute def as I've flushed the plant out so many times to correct the PH. Bio bloom only contains NPK according to the label. Went to hydro shop today for some micro nutes but they had none in. Bought a big bag of Bio-bizz soil wich is fertilized and PH'd correctly in the hope that if it is a micro nute def, there'll be some in the soil and I plan to repot her in a bigger pot.
