PK booster

[JerryMawuana]

I just bought green planets PK spike yesterday and I'm having a hard time find much info other than a little instructions section on the bottle. The NPK is 0-14-15 and it says add 0.5-1ml/L max and only a few times during flowering so that's obviously how I'm going to start. ButI'm sure someone here knows more about PK boosters. So any info would be greatly appreciated.

I’ve never used it but I know it’s supposed to be added from week 4 to 6 of flowering, after pistil budlets are formed

The flowers detect the change in PK, as a trigger.
I've used them when I get samples and only find they make the buds look bigger-

They end up with the same weight etc. once dried.

It is used as mentioned above as it can be stressful to the roots and some seed banks recomend a flush after week #5.

Thank you both for your input, but honestly now I'm more confused lol. The directions on this bottle say 'Add PK spike at a rate of 0.5-1.0ml/L to your reservoir. This will raise your EC by 0.25-0.5, adjust the nutrient strength accordingly. Apply PK spike from second week of bloom every 2 weeks until 1 week before flush.' So I'll stick with that but definitely be keeping my eyes on things.
