Late summer autos (outdoor).

Tried green house PK booster and was carefull to read instructions and watch videos. But still I managed to do a complete calcium lockout (with magnesium) in one plant and a few others also showing signs of in more or less degree. If not using tap water this product needs green house calcium!!! The day after i spotted it i got some calcium and started to treat both withe spray and in waterings. After a day i think i got it under control but alot of damage had already happen. Never in +10years have i seen such a fast disaster evolve do be carefull with green house booster! This was the week MsBloom had to die as there was no chance of veg.
