That doesn't sound like any GH feed schedule that I ever used, though it has been a while since I used GH products. On the feeding schedule, are you sure you are not looking at the amount per gallon? 2.5 ml of each per 10 liters is virtually nothing--probably give you a ppm of about 200. The formulas never had equal amounts of the 3 different parts, except during transition between veg and bloom. I used far more than 2.5 ml of each--thinking something like 15 ml veg, 10 ml micro, and 5 ml bloom per gallon for aggressive veggie growth, and then when I went to bloom, I gave them a week or two of transition where the amounts were equal and then the aggressive bloom schedule was 15 ml bloom, 10 ml, micro, and 5 ml grow. Also I believe the Lucas formula I used was 16 ml of bloom and 8 ml of micro per gallon of water. So, that is less than the regular GH feeding schedule with all 3 parts. Where did you get the figures you are using?
I never used Lucas in veg. I firmly believe that vegging plants need the nutrients in the Grow formula and if you leave it out, you are doing your plants and your grow a great disservice. I liked Flora Nova for veg.
