- At 2 weeks they're not going to show much bud, transition time.
- If you've got good soil and nutes (and water I assume) look at light and air.
- Are you ph adjusting your water after adding nutes?
- What is your all natural soil?
- Level the canopy, prop up the short plants.
- You may not be able to add more light but with bending (LST) you can max light to branches even if the plant is in flower.
- You can add an air floor to feed CO2 rich air from under your leaves through the canopy.
- I use Big Bud, Gravity and Overdrive, I find they help but Big Bud and Gravity can burn your leaves.
- What strains do you have? In the same square footage the Kali Mist on the right will produce 2x - 2.5x the yield of the Flo on the left.
