400w Club-Show Off Your 400w Pride And Joy

Ain't that the fucking truth! My goal is always to get an evenly canopy where I get growth all through the useful light zone. The better I do at that the better my yields and are. Once I have that I just try to just give the plants what they need to do their thing and they always do it really well.

Couldn't agree more.

The amount of people I tell to keep leaves green and healthy regardless of whether you prune or not is rediculous, leaf health has a big bearing on plant growth and yield.

People just don't get it though.

As you know I only use a basic set of base nutes with a couple of extra additives like Si, Ca, Mg and PK1314.

When I say I'm upwards of 400g per harvest they're like BS.


Lol.

I've killed it with Jack's 20/20/20. I'd love to have the ability to run mineral analysis on reservoir and tissue samples and see how things get absorbed and use that to formulate nutrients.
When you use the pk13/14 how much do you use when you use it?

When I get my new tent setup I'm tempted to do a run with my Blue Dream to see if I can beat 400g dry with her with a 400. I'm pretty sure she can do it.

The PK1314 I use by canna.

I use at a rate Of 1.5ml per litre at some point during week3-6 of 12/12.

Most often its used at week5 of 12/12.

sup jonda! i use a 0-9-19 last 4 weeks as instructed and i sneak it in right at the switch to 12/12. whenever i use it its at the instructed 1ml per gallon.
what ppms u guys at about half way thru?!!?

Currently I am 7 days into 12/12 and I'm running 1.6EC feed.

Water starting EC is 0.2. So my actual feed level is 1.4EC or around 750ppm @.5 and around 1050 @.7 scale.



J

My PK1314 week is usually my highest EC feed.

After that point I drop the EC back down by roughly 0.2 each week until I finish on around 0.8-1.0EC.

Then I harvest when plants are ready.


My PK1314 usage is based on plant response not a set in stone instruction booklet.


When my buds begin to fill out and start changing from pistil growth to actual calyx stacking is when I use PK.

Like I mentioned it can be anywhere from week3-6 of 12/12 for a 9 weeks of 12/12 strain.

Glockdoc I run the BD clone.
Thanks for the info Jon! I think using a standard base nute then specific boosters at specific times makes more sense than trying to stitch to a low N high P bloom food.

Agree once again.

Like I've mentioned before about what extras I use, the only "booster" I use is PK1314 for 1 week of feeding, so about 3 feeds total during that week of use.

I have switched base nute again from the 6-3-8 I was using before with 2% Ca and 1% Mg, to the canna coco specific 5-4-3 with 5% Ca and 2% Mg.

So my need to add extra Ca and Mg has been reduced for the time being.

The Si that I use, is pretty much from start to finish but all these so called "boosters" IMO are pointless if your base contains everything.

The only thing I generally have to look out for with my base nutes is Ca or Mg defs due to using coco.


IMO high P foods aren't necessary in indoor container cultivation.
Outdoors in the ground on the other hand is a different story for High P foods as the P is leached away into the surrounding area.




J

When you use it what kind of total EC are you typically hitting and how much of that is the PK?
Si has to come from an external source because you can't keep it in concentrated solution at acidic pH.

Yeah P in containers is way different from P in the ground.

Generally I keep my EC the same as it was the week before.

For instance I'm envisaging being up around 1.8EC possibly 2.0 this time around before I hit PK week. So what I do is add everything to my water like so.

Si first, Rhizotonic, ZYM, pk1314 @1.5ml per litre.

Then I add my base nute up to the EC I was before.


Make sense?



J

Yep. What's the EC of the 1.5mL/L solution?
I'm assuming the ZYM is an enzyme based product. That should be going into the mix last so it doesn't get exposed to changing conditions with respect to salinity and pH. It's not enough to totally denature the enzymes but I'd bet that some activity will be lost going through those environmental changes.

Hmm thanks for the ZYM insight.


To be honest I'm not too sure of the EC of the PK alone at 1.5ml.

I would hazard a guess at about 0.4 but next PK run I'll measure and let you know.

I'll have to try the ZYM last and see whether pH goes up or down from it.



J

I'm sure my biochem profs would be pleased to know how much I use the material from their courses these days
I'll be interested to hear how much the pk contributes to the total EC.

Here is 2 strawberry cough(left)2 liberty haze(center)2wonder woman(right)
SC and LH are 5 weeks 12/12 WW is 4 weeks 12/12
All organic under a 430w son agro

Here's a snap of my room at day 9 of 12/12.

All plants are throwing out pistils all over which means flowering will soon be kicking it hard.




Stats.
Temp hi 23.2C (this is ambient reading)
Temp lo 19.4C (ambient also)
RH hi 64%
RH lo 45%
EC in larger plants 1.6.
EC out larger plants 1.2 last time but it was first feed with 1.6. I'm expecting the OUT to be around 1.4 when I feed at 1.6 tonight.
EC in clones 1.2.
EC out clones 1.0
PH 5.8.

I'll be breaking out the dehumidifier tonight or tomorrow which will have the added bonus of not just reducing my RH ready for flowering hard, but also will increase my lo temps a little more too. I like to try and keep day and night temps with no more than a 4C difference.

With the weather getting colder and wetter here my room is running cooler with higher RH so I'm breaking out the dehumidifier about 2 weeks earlier than when I was growing in the nicer weather.

Ps Glockdoc are you running multiple lights? How many plants in those pics? How many plants per light if using multiple?


Nice buddage!!!!!!

thank you jonda very much appreciated!

im using 1 400W hps in a 3ft W 1.5ft D 5.5 ft T cab for around 88w per sg ft

feeding maxibloom roots organic , budda bloom , a blossom builder 0-9-19 at 1000ppm as of last week

veg nutes where ionic grow and general hydroponics grow nutes ppms 400-500, veg'd under 400 for about a month for bigger plants 2 weeks on smaller headband plants. chemXmat had month veg just stayed small probably because of 6 plants in a container and genetics, got plenty more beans of it and next run will involve a good amount of chemXmat and headbands with a hso pineapple skunk and something else probably run a femaleseed$ fem mix.


still supplementing micro
used superthrive during veg every couple weeks
hard tap water but still supplement cal/mag
molasses grandma's robust

FFOF soil

Peace

Nice.

So how many plants was that? Lol.


Just watered.

HSO PS in 1.5 out 1.2
HSO og in 1.5 out 1.3
Critical+ in 1.5 out 1.1.

Clones didn't need watering.






Hand in shot for size comparison of my canopy.





J

7 total there is a runt headband that cannot be seen, 4 weeks in hasnt even thrown out pistils due to it being sooo damn small that it gets no light under that forest .

critical is a pig eh?!
