When To Use Pk 13/14....??

[Newbie987]

Hey Guys,
I am doing my first set up and im in week 3 of flower. I have amnesia haze and ive got about another 7 weeks minimum. When should i use the Pk? ive seen people use it in week 3 for a good start into flower and then in week 6 for a week for full potential for best yield. I will be using vitalink pk 13/14.
Anyone used this and have some advice.

Thanks guys!

I like to use it in the beginning, middle and anywhere up to flush.... 3 times should do the trick.... and a little goes a long way... dont go by the back of the bottle right off the bat... cut it in half and see if it burns first

It say 1ml a litre so I'll just use 2ml a gallon

Ya start small... you can add more later but you cant take it back after you fried the plant.

2ml a gallons about .5ml a litre so will be fine there

Hello guys!
I have a question that is similar to this, i hope you can give me some input.
I bought ATA-XL from Atami. Its PK 2-2 and it says "as of the third week up to the final week of the cultivation.". Its 3rd week of flower or vegetative?

This for most pk boost products out there. Ideally you want a slight (very) increase in phosphorus in early flower (it will increase stretch) and calcium. At mid flower you want more magnesium and mid to late flower you want that potassium magnesium and sulphur. Back off the calcium once buds are ripening. But really phosphorus is in its most demand in early flower. Pk boosters are ball park really. That's why growers just add in small amounts all throughout. But if u can seperate the 2 and really know your strain then adding certain minerals at certain times is much more effective.

Nitrogen increases stretch by cell elongation ... pk booster prevents stretch.... i run a 7 feed (2 products) system on a lot of plants and a pk boost day one is include ... and 2/3 week leach

Yes..but phosphorus is the real culprit with early flower stretch. Tissue analysis proves it. Nitrogen makes for bendy flexy apical dominance. Lack of sugary carbs. Energy spending. And nitrates are different. Ammonium nitrate is a whole different game.
