AsNoriuanswered grow question 4 years ago First you have to heal your girl before any thoughts about flower is even made.
Bigger plant in veg - bigger fruits, that works in any garden.
With 8 weeks of veg in soil you should harvest from 80 to 150 g from plant .
But, bigger plant means longer used soil. If you make mistake it is easier to correct in soil, but you have to know what and when.
2 feeds a week is too much, maybe thats the answer to your girls condition ?
Think about flushing her and maybe giving bigger house before flowering ?
New soil should be more stable with ph, which i guess you disturbed in your current pot.
All the best !
