Either your pH is off or your EC is way too low...

What's your pH?
What's your EC?

 

[soyokaze]

my ph is 6.0, but i don't know what my EC is.. ihave a ppm of 1200

I would start out with a damm good flushing and really make sure you get your whole rez cleaned out well, scrub it down and fill it up a couple times after your flush. Then hit it with your nuts again starting at 5.8 ph at about 1400 to 1500 ppm's. Thats just my opion and they are like asshole's, everyones got one.
Good luck.

I found this on their website...

Bloom stage elemental ppm using 10 ml. Base Formula, and 20 ml. Bloom Formula per 4 liters (1 gallon) of water:

N 105, P 208, K 184, Ca 100, Mg 50, S 46, B 2.5, Si 45, Fe 10, Mn 6.5,
Zn 1, Cu .01, Mo .008

This fert is nuts! P at 208 is bonkers! B at 2.5 is toxic. This will kill your plants outright. Mn at 6.5 is way too much. Zn at 1 is really high. And comparing cu to zn, its 1:100 ratio. Should be about 1:2 or 1:3. Cu at .01 is too little. So is mo at .008

No wonder your plants are screwed up.

.. B at 2.5 is toxic. This will kill your plants outright..

Ive used the stuff and yea the factory req dosing is waaay to high for mj. kick it down to 1/4 and move up to 1/2 but i wouldnt go past that or else your gona have some brown dry crispy plants.

i AGREE Tri Flex is junk.... I am having so much trouble with the shit right now.... Im headed back to Fox Farm next time im switching to Pure Blend PRo.

I would use more nitrogen in your system, you have a nitrogen problem going.......

WHat is your water temps and pH? How often do you test them?

When did you switch over to your bloom nutrients? Right when you put them into 12/12 or did you wait?
