Suplementing flowering in Coco/CNS17

Hi everyone, long time reader but never felt the need to write anything till now. I need general input and suggestions because I'm on 2nd week of flower and this period is crucial.

Currently working with the following:
In have in a 4x2 tent the following
1 x Kandy Kush and 1 x Nebula in Large autopots, 60% Coco and 40% Perlite
1 x Holy Grail kush 3 gallon smartpot with a 50/50 coco hydroton mix

Growing under ScroG

They are under 2 x chinese 300w LEDS 12/12 (they love it), after vegging for 4 weeks under an 8 lamp Quantum Badboy T5 on 20/4.

Scrog net is nearly full with nothing but tops, looking healthy.

RO Water

Rez PH between 5.5-5.8

Nutes:
Vegged Beautifully with CNS 17 Grow + CalMag + Liquid Karma

Blooming with CNS 17 Bloom + CalMag + Liquid Karma, and just started adding a few days ago Liquid KoolBloom (store didnt have Hydroplex in stock). My Total NPK is 2-12-13, and currently PPM is at 1170.

Also doing a preventive 7 day under canopy neem oil spray.

Just wondering if my ratios are on spot given the conditions.

Planning on using CNS17 Ripe, Karma and Calmag in the final 2 weeks before flush, should I continue with the liquid koolbloom and molasses for a light PK/carb boost, or go gung ho with Dry KoolBloom/MOAB/Shooting Powder?

Npk of 2-12-13???

This is the weirdest ratio I've ever heard of.

Exceedingly high K considering coco produces its own K over time.

Very little N to sustain healthy foliage.

Far too much P to be useful.

And you want to add more P and K???

I would be looking to cut back on the P and K and increase the N.

I would ditch the koolbloom.
Cns-17 rocks. I used it for about 2yrs.
Use the grow for veg.
Use the grow for first 1~2 weeks of flower.
Use bloom the rest of flower, until 3 weeks before chop time.
Use ripe the last 3 weeks.

No need to go changing the numbers up.
The ONLY thing that MIGHT be beneficial for you plants, besides the cns-17, is the calmag. I saw no increase in yeilds from messing around with the liquidkarma.

Growing in coco, and starting with RO water, I used 1/2 tsp of calmag, plus 1tbsp(3tsp)MAX, of the cns-17 per gal. Thats it! Trust me

Well the logic was that the NPK ratio of liquid koolbloom (0-10-10) is "nearly" the same as hydroplex (0-10-6) , the recommended bloomer for CNS17. Also thinking of PK 13/14, my ratio is not that off. The autopots only bottom feed in the lower 2 inches of the container., so whatever K present in the media is being partially absorbed.
Low N means shedding of foliage and concentrating on the sea of tops I have above the sceen.

My logic is sound?

If your gonna PK boost, it is usually done at the end of flowering;-)
Hydroplex is a PK boost yeah. You would add that to the bloom formula(at the end of flowering) if you don't have the Ripe. Ripe is a complete 1-part flowering formula, plus a PK boost, if you will.
You do not want to "shed" leaves. Or even "try" to yellow them up at the end. That is old school bullshit advice IMO.
I wouldn't even switch over to the ripe formula, unless your leaves are healthy/green. The bloom will work fantastic all the way to the end, all by itself, BTW;-)

I use a 5-4-3 from start to finish.

I add a PK boost if I feel the plants can utilise it (ie P or K def symptoms)

The biggest things I use in my arsenal besides my base nute are extra Ca and Mg.

If I use a PK booster to try to enhance the flowering phase then its used at some point between week5 and week 7 of 12/12 on a typical 9 week flowering period. I can't tell you exactly when because there is no destined week to use it. It is governed by the plant.

Some strains benefit at week 5 others at week 6 or 7.

Most people experience over use of PK boosters because the N, Ca and Mg are generally lacking to make use of the added PK.

Usually last 3 weeks of flowering is how we have always done it.(all the people I know in the bay area). I used to acheive a "pk boost" 23 yrs ago by going 1 part micro, 3-4 parts bloom. It used to be on the label. I'm curently back with the flora series, and pk the same way(when I feel like it)

I would add some type of enzyme concentrate like Hygrozyme or Sensizym you got carbohydrates in Liquid Karma enzymes and carbohydrates great for plants during flowering

why are you using molasses in hydro? The whole point of molasses is to feed soil bacteria. But i guess if it aint broke, dont fix it.

I will suggest that your nitrogen is pretty low, and think you'll see yellowing and early drop of fan leaves if you stick with that ratio
