You could easily move to 600PPM. With the cl/mg you will have to verify your pH is 5.8.

Appreciated!
Just changed water. 6ml calmag, 1/2 nute strenght @ 12L water. Ph around 5.5-6 id guess. (Using colorcode) Landed on 566 ppm. Im exited about trying out the calmag for the first time!

Abit confused againā¦
So im recieving some voodoo juice in a couple days.
And Lets say im going for the 600ppm mark for next weeks waterchange again.
How much voodoo should i use? The recommended 2ml pr L would k.o the plant for sure.
Should i go half on the base nutrients (GH 3 part) and then add voodoo to reach 600 ? How would i get the most benefit out of it?
apologies for my professional questions 
@dbrn32 @WickedAle @Myfriendis410
All I use is the GH 3part and armor Sl. Nothing else. So canāt help you with all the other additives.

Iām not a hydro grower, nor do I use any of those products. So I donāt really have first hand knowledge to share on them. However, you could just mix up and see where youāre at. If your results are higher than target ppm just add water until you get to the 600ppm.

Thatās ok, for a 3x3 I really like horticulture lighting group qb 260 xw kit. Thereās a lot of good lights available, but I feel that will give you really good value and excellent yield potential in a 3x3.

Not sure what your situation is and what is available to you for lights. @dbrn32 has a staggeringly comprehensive knowledge on lights and is the exact person to talk to about them.
As far as the Amazon lights go; the Mars Hydro lights are as good as any. You will want more rather than less if nothing more than for the coverage.

I ended up with buying a Mars Hydro II 400w. Probably recieving it in a week or so. Pretty exited about that.
What does these pictures tell you guys?
Overfeeding? Short on calmag? Maybe both? 
Ive been gradually going down from 600ppm->330ppm and just lowered it to 255ppm.
May have been a little high on ppm earlier but upper stuff looks pretty good.

Also, do you have any experience with mars hydro light?
It comes with a mode for veg and one for bloom. Iāve been reading some ppl just go full power from start to finish. Whats your take on that ?

Depends on size of light and size of space. In most cases I would probably run them both on.

Your plant looks fine. They will like the nutrient level you are setting.

Its gonna take me a while before Iāll understand how lights work.
Would the Mars Hydro 400w be a good upgrade from this one?:
Lumeri PNLW 400
400 Watt (400 LEDs x 1W)
Red (625-630 nm) - 316 LEDs
Blue (445-470 nm) - 56 LEDs
White (6500 K) - 10 LEDs
Varm white (3500 K) - 10 LEDs
IR (730 nm) - 4 LEDs
UV (380 nm) - 4 LEDs
I couldnāt find listing on that light, rough guess is that they are probably similar

Got this badboy yesterday. It was a beutiful upgrade compared to size and quality of light from the current cheaper 400w led ive used.
Ive been introducing a digital timer the last week for 18/6 Light schedule just to keep the temperatures lower at daytime. But when the timer is off there is a tiny amount of light coming from the LED. Is this normal/safe ?
