I haven't used bio bizz light but from what I know of it it's close to promix with little to no nutes. With the size of your plant and no nutes in your soil you can start @ 1ml/L, I start mine @ 1ml/L @ day 10 and feed .5L feed per plant. And I know it is very confusing it was to me too when using the 3 part system but the G/ m / b base nutrients are designed to use @ a 1/ 1 / 1 ratio from grow all the way through bloom you can see this on the advanced nutrient calculator provided on their website
I don't use cal mag til the bloom phase gets going. Reason is I have never ha any type of cal mag def during my veg phase. And the 3 part grow micro bloom is used the whole time because basically they are base nutrients needed in all phases of life. If you look at the NPK rating added up its not near as high as some bloom nutes. That I'd why big bud and overdrive are added for bloom if you then add the NPK up on overdrive it's a good but higher to support bloom.
And as far as run off I do not water to run off. Some do some don't I got that from tang and then after I thought further into it I can soak my pot wit a certain amount with out runoff and conserve nutes. AN is a great line but I'm my mind there too expensive to run 15% into a catch pan. And I can tell ya in my experience with promix at the size of you plant I give .5L every day or 1.5 days
thanks for your inputat this stage the curling is kinda normal. looks real nice and healthy
