That pic link is a total mindf*ck. It took me to my gallery. Well it's not P. I was leaning heavily toward K and then I read that you added dolomite so now I'm leaning even more heavily toward K. If they were my plants, I would hit them with some foliar potassium silicate (Dyna-Gro ProTekt or Silica blast). Anyone agree or disagree?
do you think your ph is good?
How much dolomite did you add? Using tap water? Do you know the ph of your plain water? Do you bubble it to get the chlorine out? Do you ph adjust it after nutes and when used on it's own? All these alkaline factors will raise the ph of the medium...peat does need some balancing, but promix is already balanced out with lime, correct?
That article is true but fails to mention anything about water used and it's properties...if using RO water with a ph closer to ideal, you can have success naturally but it is complete bullshit and a zombie lie out there that ph is not important in soil. PH is important to every living thing. If your tap water is PH 8, you better believe it is gonna affect your plants negatively. 6.3 is where you want your soil ph and water/nute solution.
Anyways, even for troubleshooting, when you know the ph is correct you can look to other causes and solve the problem quickly and efficiently.....
Why don't you fill out this form so peeps here can help you better:
SOIL:

What size pots are you using? (Include how many subjects to pot)
What substrate/medium are you using? What brand of soil mixture are you using?(percentage of perlite, vermiculite...etc?)
What Nutrient's are you using?
How much of each nutrient are you using with how much water? *Knowing the brand is very helpful*
How often are you feeding?
If flowering, when did you switch over to using Bloom nutrients?
What order are you mixing your nutrients? (example: veg nutes 1st, bloom 2nd ect)
What is the TDS/EC/PPM of your nutrients used?
What is the pH of the "RUN-OFF"?
What method of pH test was administered? Using Strips? pH pen?
How often are you watering?
When was your last feeding and how often are you feeding?

What is the current Air Flow? (cfm etc.)
Tell us about your ventilation, intake exhaust and when its running and not running ?
Is the fan blowing directly at plants?
Is the grow substrate constantly wet or moist?
Is your water HARD or SOFT?
What water are you using? Reverse Osmosis (RO)? Tap? Bottled? Well water? Distilled? Mineral Water?
Are you using water from a water softener?
Has plant been recently pruned, cloned or pinched?
Have any pest chemicals been used? If so what and when?
Are plant's infected with pest's?

SOIL:
How long has this problem been going on? A couple days
What STRAIN are you growing? Purple Kush
What was the establishing technique? (seed or clone?) Clone
What is the age of your plants? Almost 2 week old clone
How long have they been in the soil mixture they are in now? 1 week
How Tall are the plants? 4-9 Inch
What PHASE (seedling, vegetative or flower) are the plants in? Veg
What size pots are you using? (Include how many subjects to pot) 1 Plant per 1 Dixie Cup
What substrate/medium are you using? What brand of soil mixture are you using?(percentage of perlite, vermiculite...etc?) LC Soil MIx 2 (6 Part Promix, 2 Part Perlite, 2 Part Worm Castings, 1 Cup of Dolomite lime per 1 cub feet of soil)
What Nutrient's are you using? Plain RO water and EWC Tea (No molasses)
How often are you watering? Once 2 days or so when they need watering, when they dry out
Under 8 T5 Lights
What is your RH Factor? (Relative Humidity) 45%
What is the canopy temperature? 75 F
What is the Day/Night Temp? (Include fluctuation range) 5 Degrees
What water are you using? Reverse Osmosis (RO)? Tap? Bottled? Well water? Distilled? Mineral Water? RO @ 10 PPM
Are plant's infected with pest's? NO
Summary:
Clones went into LC soilmix 2 (6 Parts Promix (5.9pH out of the bag), 2 Parts wormcastings, 2 parts perlite, 1-2 TBSP dolomite lime per gallon)
Fed with EarthWorm Casting tea only (No molasses) ALL plants look very green and healthy BUT the purple kush look like this.
Using R/o water ph coming out at 5.8 @ 10 PPM. Earth Worm Casting has Guaranteed analysis of 0.87 - 0.36 - 0.25
I am guessing it is because it is underfed and I need to starting brewing the veg tea?
Drow, ph is important what ever system you choose to grow in,
but, outdoor grows it's not too often to see pH issues.
Now with this one, I wanted to first say; drow you have 2 of the best helpers on this site helping ya with your problem, take there advice, I vouche for them anytime any day of the week/year!
This one is difficult for a few reasons... I see more than one problem occuring here...... your plants show like they have not much food, like
but it also seems like it wants to show a potassium/ calcium issue mimic calcium
With you using RO water and no micronutrients chances are you do have a problem....
as for the rest of the plant's problems you may be giving it slightly too much.... have you tried feeding it and no work?
How often have you fed this plant?
REason why this one is having issues and the others are not is, because they are different strains and strains are like people, some can handle more than others... same goes for them with there environment factors like too much food, easy light burn and so forth some are more tolerant to high nutes where some get the slight issue and they go crazy!
