Going to switch to flowering

They look ready to flip. Just don't let veg grow so high that after flower stretch you can't maintain canopy. https://www.growweedeasy.com/flowering-stretch

If you're serious about getting good flowers, focus on fixing those deficiencies first. No point chasing big buds with stressed plants. Get them healthy, then worry about stacking flower.

Maybe give them a little less water

Good job
