When and how much pk boost

[Josh]

So I'm a little over 2 weeks into flower, and according to ionic I should use pk boost from weeks 4-7 at a rate of 1.5 to 2 ml per liter.
My main question for you all- should I add the pk boost first at the recommended amount, and then add my bloom until I hit my target EC?

Also, when is the best time to start using it? Week 4 seems a little late to me, because by week 3 with this strain I'll have full pom poms and the stretch will be over. Which means flowers will be needing that pk the most correct??

Lots of different oppinions on this subject, excited to hear what everyone has to say thanks in advance

I'm in coco Josh, so maybe different but I use the pk 13/14 from day of flip for 2 weeks, then a 4/10 for the rest of flower.

Pk boost should be used week 2 to 7 at a rate of 0.5-1ml/l :)

If PK is overdosed at early stage of flowering it can stall the plant and cause early maturing. You have to start very low and judge by the plant development.
In coco that's the main reason I am doing midflower flush. To flush the excess salts built by the early PK use.

its plant dependant mun no 2 strains take on board the same amounts...... imo less than ive used my chiesel has suffered where as the others loving it !!!

Hmmm, lots of good points here. Thanks for all the responses guys
So I'm pretty dead set on using the ionic pk boost, I believe it's 13/14
So I guess I should start at a low dose and see how the plant responds? I'll do .5 ml/L like Nanook suggested

How will I know when I'm overdoing pk?
I'm only good at identifying nitrogen and Calcium deficiency/toxicity

Gonna give this a go thanks mate
