Help! How can i fatten these buds up?

[Clandestino]

Hello everyone, i feel like my buds are still quite small maybe someone can help me out so i can make them grow bigger.
Here are some pictures ( i am not the best at taking pictures, sorry for that )

The strain is called ’ blueberry headband ’
It has now been 45 days since i flipped the light to 12/12.

My tent is 120cm x 240cm

The lights are 1x 450watt mars hydro 1x 350watt mars hydro and 1x 100watt spider farmer ( LED,full spectrum)

I use Terra Aquatica nutrients (GHE), tripart + calmag + fulvic + oligo spectrum (macro)
Here ist a list of when i switched out the nutrient solution in my dwc system with ppm and ph :

I usually go by the chart but the last time i only gave them 75% strength.

I usually have about 22 degrees Celsius and 50% relativ humidity.

The plants are in self build dwc containers with a volume of approx. 60L for two plants.

I am thankfull for any help
Happy growing

Your flowers are very healthy and will continue to pack on weight for the next couple of weeks.

For the best results focus on the basics (pH, PPM, intense lighting, and so on.)

Alright thank you guys @MidwestGuy @Reed71 , do you think i could go higher in ppm or would that be to much ?
What do you think about adding a PK booster ?

[MidwestGuy]

@Clandestino

higher in ppm

Maintain a runoff PPM of ~1,000.

@Clandestino

PK booster

These are unnecessary and can cause more problems than they are worth. They can create salt buildups making it hard to manage pH and they throw off the NPK ratio of your PPM measurements, making it hard to meet adequate nitrogen levels when maintaining a reasonable PPM.

@MidwestGuy should i just mesure the solution that is left in my reservoir when changing it ?
Ok thank you

[MidwestGuy]

@Clandestino

mesure the solution that is left in my reservoir

Maintain a PPM of 1,000 in your reservoir.
