Koolbloom with Lucas formula

I’m growing a critical mass and a power plant using lucas formula. I’m 37 days into flower with power plant and 23 days for critical mass.

I have some liquid koolbloom that I’m wondering how to use with lucas formula. Should I add koolbloom to what I’m already feeding or do I substitute florabloom with koolbloom?

Just looking at the elemental ppm…

Lucas already has a good amount of P and K.

GH Liquid KB in this table.
Shows P and K ppm per ml per gal.

Beautiful plants!
Are they in coco?
Feed EC? PH. Freq?

Thanks for response and info.

Plants are in Sunshine #4, EC .750 (scale 500?) or around 1300-1500 ppm with 8/16 micro/bloom and cal/mag added to RO. PH 5.8 to 6.0 in and out. I feed/water/feed/water to a significant runoff.

I ran this this same thing on my last grow (runtz) and grow was successful, however I thought buds could have been a little bigger. So I was wondering if upping P/K with koolbloom might help buds fatten some?

@GramTorino where did you get those nute matrix charts? Or something you made?Either way any chance I can get a copy :pray:.

I use spreadsheets to document nutes. I do my best to keep things accurate.

You should be able to download the images posted above.

@Dirtron What nutes are you using? I can drop you a spreadsheet if that’s what you need.

No experience using Sunshine. Only coco. But I always feed, never plain water.

Hopefully others here have better insight using the same medium.
