Just started using bio bizz. Everything went fine in veg.When switch to flower added the bloom. Brunt the tips only added two mil per litre. What is a good mil between bloom and veg.
if im using BB ferts i run them 4-6 ml per L depending on size and strain of the plant, 2 ml would have mt room yellow in no no time. you may have other underlying issues with soil
I would have to agree with Guy Fawkes on this. There is an underlying issue with the soil.
Maybe a buildup of nitrogen, from the sound of it.
If this is the issue, it would cause nutrient burn and a possible nutrient lock out.
