can someone send me the link or post the picture plz
it would be well appreciated
thx

Ive been running my hydro system at 6.0, the chart says that it bad, should I change this, or is the chart old hence the experimental?

How about this?

I think most growers set thier PH a little lower, then allow it to rise on its own. As it rises, it allows uptake of all the nutrients

6.0 is a lil high. 5.5-5.7 is ideal.

Holding steady at 5.5-5.7 can lead to magnesium defeciancies. I slightly overfeed with slightly alkaline water (6.0). Over a two week period, EC climbs and pH drops to 5.6, Four gallons of straight tap water brings me back to original numbers.

OMFG can someone explain to me why the 2 ph chart differs from each other.
the first one shows PH above 5.5 cuts phosphorous and the other chart shows the opposite.
and why in the world do different strains of marijuanna show different symptoms when they have defficiency if its the same god damn plant.
and why... you wouldnt even believe me so I wont even mention it

sure...one is for soil and the other is for hydroponics.

The two charts aren't directly comparable. The B&W is for plants in general, uses tapered bars and uses .5 increments. The color chart is for marijuana, uses flat bottom bars with 0.2-2.0 increments. I'd trust the color model first. It's specific to MJ and the B&W chart is WRONG when it says "pH above 5.5 locks out Phosphorous and Magnesium." I locked my DWC in at 5.5 and was rewarded with a garden wide Mag deficiency. Raising pH and allowing a swing between 5.6-6.0 returned Magnesium to the plants.

Different strains have different needs because, well, they're different strains. MJ has been developing itself for 10,000-20,000 years. It's only been in the labs of Holland for a couple of seconds on the universal clock. Takes longer than that to give up thousands of years of training. Plants are as individual as people. Some have red hair, some have green eyes, some are tall, short, fat, thin, diabetic, blind ...

can we get that color image a bit bigger? I can't read anything on that...

And just to make sure everyones as confused as possible, have another.
