Feeding seed plants

[spacetraveller]

Over the next couple of months i intend to make some seeds from pure sativa plants.
I grow indoors using run to waste hydroponics.
What nutrients/additives would you suggest for my seed plants?
My thoughts are grow A and B for the whole cycle, no additives, what do you think?
Thanks in advance for responses!

I feed seed plants till the end with various nutrients.

I don't feed seedlings for 2weeks .edit thought it was about seedlings

Phosphorous especially is needed for seed production from what I understand. The grow fertilizer will have some but maybe you would be better off using a bloom fertilizer instead.

I feed more nitrogen in the middle of flower if I intend on making seeds.

I feed a balanced moderate nutrient with both N and K level up until harvest when feeding seed mothers.
