1. I don't know what liquid nutrients you're giving them
You should use late flowering/bloom food. A low concentration of 0.4 EC high P/K nutrients like Green Sensation, Atami B'Cuzz, Canna PK 13/14.
2. Transplant into a larger pot.
This will really increase bud size if you transplant just into flower.
When you transplant, always transplant into a soil that is less hot than the medium the plant is in right now. If it is, fill the pot with hot soil, then 1 inch of light soil, put the plant on top of that and fill in the sides with more light soil. Then water with 0.4 EC of high PK nutrients and 0.1 EC of epsom salt (Mg for the leaves).
Don't mess with the roots at all other than holding the rootball for support.
This will prevent transplant shock, which is not a good thing in flowering. The plants will recover in hours.
When root growth happens during flowering, it supports the growth of flowers instead of branches and leaves. That's also the big difference between hydroponics and soil, in hydro the roots can grow into water unobstructed, while in soil you have to create extra root space by transplanting or topping up pots with flowering soil.
3. When to water
When you water the medium, do it slowly and thoroughly, and see how much water the soil can hold.
Then don't water again until the top of the soil is no longer wet before the lights go on or the sun comes up.
Think of it as the plant getting watered by evaporation.
This way you'll never overwater or underwater. It's also dynamic because it compensates for changes in humidity or growth of the plant. No schedule, except the one set by the plant and the environment.
