• Shake bottle well before use
• Add CANNA PK 13/14 three weeks before harvesting to a full nutrition tank in the following proportion: dissolve 15 ml concentrate per 10 litre of water (1:666). Add this mixture to the nutrient for 3-6 days

NO pk 13/14 until well and deep into flower!!!!!! There is actually a small window in which to use this product and veg isn't the time.

This is from canna instructions.

I have been running hydro off and on for many years and have used canna nutes quite a bit. Heed my warning or you will have a myriad of issues arise. And typically you only use it for a week no more no less!!!

Heres a link, watch the video http://www.cannagardening.com/pk_13_14

And in figuring when to use you need to know what the flower time is for the strain your running. Typically round week 5 of flower in an 8 week strain. Sativas and longer flowertimes you would have to adjust further out than 5 weeks.

I would be trimming the bottom of the plant to divert the energy to the top bud sites (look up lollipopping)and putting a rigid net over your plant the shape of a stadium(look up scrog). As your plant is finishing filling the net bring your lights gradually down to 12/12.

I couldn’t see the bottom of your plant so I didn’t realize. I would also defoil some of your fan leaves. When light penetrates a leaf most of the light spectrums absorbed, the tiny bit of green that gets through hits the leaf underneath and causes it to close it’s stomata which pushes the energy to the upper leaves receiving the fuller spectrum. You’ve took the time to grow a big bushy plant you may aswel give your plant some depth rather than only the upper 10% getting light.

If I don't make a huge mistake, with 600w light How much dry harvest do I get? This is my first grow and I am very excited.
