Hi guys! I have this question, on a regular 8/9 week strain, nutrient companies tells you to add PK on the 4th week.
I got a 12 week strain (Amnesia Haze) so, should I give the PK only on the 6th week? :roll:

I was wondering the same thing dude, growing Kali Mist and she's a 12 weeks strain. Well on my Coco grow schedule (Plant Magic) it says feed for 3 weeks (4th to 6th) on a 9 week grow. So basically feed it for a third of it's flowering time, 1/3 of 12 is 4. So feed from the 4th to the 7th week.

Personally on anything over 10week flowering its best to use PK13/14 a couple of times at least.

On 9week flowering I use PK during weeks 3 and 6 at full strength and in between 3-6 I use it at 1/3 recommended dosage.

On 12 weeks I would use it at week4 week7 and maybe week9.

This would be my minimum if it were me doing a 12 week strain.


Also during PK weeks I like to increase Ca and Mg due to the added P and K the plants really love the extra Ca and Mg during those times. But that's just me lol.

been staggering it and my plant is loving it. i'm on a tight budget and almost skipped the pk 1314 entirely, and just ran the a+b, but i read to many good benefits from growers using the 13 14 and cannazyme, so thats wat i went with. skipped on the boost, and the rhizo. i sub bioroot in its place, works great
