Determining the right PPM in late flower

Hi all, I'm entering week 7 of flower on my first grow. Critical Kush in a RDWC setup with HLG 135 QB. GH trio plus calmag and silica.

Currently running about 800 PPM. No signs of deficiency, but I don't see the buds fattening up as much as I expected.

Any tips for dialing in your late flower nute regimen?

Plant looks fine. Keep doing what you're doing. Plant looks healthy keep it that way. It looks like it has some time to go. It will fatten up.

I usually start tapering down the nutrient strength towards the end of flower. But I'm growing in coco.

Make your own PK booster with some Potassium Sulfate and Monopotassium Phosphate. Blend those to get the PK ratio that you desire when combined with your nutrients. Keep the K higher than the P so as to maintain quality (flavor and potency). There is a nutrient calculator spreadsheet that I made, I will add it here. You can use that to see how your nutrients pan out. It will calculate the elemental PPM of your various nutrients.
