Green gelato auto rqs organic

Ok so we have a definite deficiency... think it's magnesium and nitrogen so I've added epsom salts and gave a light feed of bio bizz to try and get that healthy dark green colour back. Not sure what's happened but it seems as soon as I drop the grow formula dry amendments, everything goes to shit... same thing happened last time so I won't be using the bloom alone again. There is an auto version just been brought out from living soils, so I'll use them next time round. Buds are getting huge now despite the issues, overall its not been a bad week just having a few issues. Hopefully I'll get on top of them soon and all will return to normal.
