I talk dirty to mine and that seems to help.

I tried that. Now they shut the light off when I open the tent!

Just moved a chrimera into flower. Will keep an eye on it.

My mother's, chimera 3 and LA pure Kush, are green as green can be. This happened 4 weeks into flower.

I have one that has only been in 2 weeks, (extra mother) starting to flower, still green as green.

Mother's and veg are ph 5.8 with AN grow nute. Problem happened 4 weeks into flower.

So, made up some 6.6-7.2 or so water with cal mag only, for past couple waterings. Seems to be helping getting no worse. Lone plant in 4x2 was just starting to show some of the yellow with dots, it's now doing fine.

The others just had a few yellow with dots leaves, all new growth is fine.

Those links show the chemical contents of jacks pro,perlite and peat.
Also shows why it works and that the assumptions being made regards "cal-mag" are just that.........assumptions.

Say, I noticed Jack's has a cannabis specific product. I did not look at it's make up. Obviously there is a reason to use "Professional" 20-20-20? I also was on their site, which didn't show prices, maybe it "priced" for cannabis market?

Also saw a "Classic" 20-20-20. Not sure how it varies, but the Professional version is what you use, right?

I use the jacks pro 20-20-20 I usually get 25# bags from Amazon.
That lasts about 18 months running 8k. hps flower.

 

[boo]

8K HPS is like having a sun indoors, care to elaborate on your setup…I ran 4K HPS years ago and was getting 1.58GPW but my power bill was insane…

I can only run my hps in the winter the way I'm set up. Even the led wants to push high 80s.

Our elec rates are .058 cents A kw.
I run two 1000's in Cooltubes in 5x10 tents.
I use 440 cfm inlines to move the air through the tubes with passive intake.
I use tents cuz yields drop per kW when I don't.
Veg under 400 hps cuts in a aerotype cloner.......really simple and basic.

 

[boo]

my power bills were .071 per kw and they add .059 for fuel as a surcharge...I can buy superb flowers for 60 bucks a zip from a friend whereas it cost me $2500 in power to run 5 months...it's just not cost effective for the size grow I had...400sf.

Sorry yes I use sunshine mix#4,jacks pro 20-20-20 at 1\2 tsp. per gallon tap water which comes out to 3-3-3 roughly.
Every water until the very end of flower then just plain water the last week or so.
Perfect,healthy plants no Ph adjustments no flushes no ****** calmag.........just healthy plants.

Making sure I'm clear, you give this 1/2 teaspoon per gallon every time you water, don't stop until last week or so.....no just plain water, right? Had to ask, or I will try them to the bone! .

 

[Bubba]

Funny thing, I had "General Hydroponics" cal mag. I got some "General Organics" cal mag that pute suggested and uses. It is organic, the other isn't. BUT they both come from the same place, and have the same logo on the bottle.

I mixed up 2 separate gallon jugs, 5ml in each, shook and measured. The water was 7.0 ish to start with. The "Hydroponics" version lowered ph slightly, about 6.4 or so.

The "Organics" version lowered pH to about 5.5.

Yes every time until the last week then just water.
