Its nice when its an easy fix. Its a deficiency.
POTS are drying out between feeds or pots are too small.. Consistant and regular feeds maby 3 times aday till about 15% waste and re pot into fresh soil and pot 3 times the size and they will improve and flower well.
I often see this yellowing or paleing starting from LoWer on the plant with/in my mother plants when i get alittle slack...

They do look hungry; but to be sure it's not something else causing it' can you please fill out these questions?
The more ya fill out the better we can help you out in solving what is wrong.
SOIL:
What STRAIN are you growing?
What was the establishing technique? (seed or clone?)
What is the age of your plants?
How Tall are the plants?
What PHASE (seedling, vegetative or flower) are the plants in?
What Technique are you using? (SOG, SCROG etc)
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 with how much water? How Often? *Knowing the brand is very helpful*
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 size bulb are you using?
What is the distance to the canopy?
What is your RH Factor? (Relative Humidity)
What is the canopy temperature?
What is the Day/Night Temp? (Include fluctuation range)
What is the current Air Flow? (cfm etc.)
Is the fan blowing directly at plants?
Is the grow substrate constantly wet or moist?
Is your water HARD or SOFT?
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?
Those plants do look like they may be getting a little root bound...... what size pots are they?

ok nutes used is iguana juice from advanced with grozyme, humic acid,. plants are in 1 gallon bags a few are in three gallon bags, thier is a couple one gallons with two plants
yes they where cloned about four days ago. humidity is about 45 percent, i am growing a large mix of strains, this run is for finding mothers hence some of the plants cramped together i wanted the numbers in selection. canopy temp is about 80 degrees
they are all from seed 18 days flower. water is reverse osmosis . The medium is promix hp with about 30 percent added perlite. ph of the food or water is 6.2 6.1. i tested the run off and it was 6.0. Ph pen used. ther is a muffin fan and a computer fan that blow directly on the plants. the exhaust fan was rated at 500 cfm but after it pulls through my carbon filter probally about 300 cfm. as for the tds did not test it i heard organics are not read properly by tds meter. but at day five flower they got thier first food at about 1/4 strength, then a week later about half strength. and i bumped it up a lil more the last feeding about 1.6ml per liter. the distance from the 400hps to the canopy is about 8 inches for some plants maybe a 1.5 feet for others but those are hit by side cfl lighting. night time temperatures where dropping to about 62 degrees untill last week i put in a large heat meat that goes on and off durring night cycle to keep the soil from getting cold temps of the soil seem to be perfect now not cold to the touch.

Being that this effects the lower leaves tells me it is a nitrogen deficiency.
thier is a couple one gallons with two plants
Are the ones having issues is the ones with more than 1 plant?
You using the grow or bloom? Most likely bloom right?
I don't know if you know this; but the soil is supposed to be kept cold; not warm; warm soil temps invite bacteria and such you don't want that.
With advanced nutrients normally you can listen to there directions they give since it's based on cannabis plants.......
but like og says it does look like a nitrogen issue going on......
How far into flowering are they? from day 1 you flipped to 12/12..
how tall are the plants?

hey stitch they veged for about two weeks then flipped to 12/12 on the 19th day of flower. the soil is still cool but its not cold some of the plants are just over a foot tall. the doubles dont seem to be affected more than the singles. i have three white rhino lowryders in a 3 gallon that are not affected . i flushed them two nights ago and it doesnt seem to be getting better it almost looks like they are burning more some of the tips of the yellowing leaves. and i dont think its nitrogen or nitrogen only cause thier is some dark splotches on some of the yellowing leaves aswell and one of the plants the bottom leaf almost completely yellow but it was green around the edges. i will post up a pic in the evening

What are your temps like in there day and night. One thing I will say is a problem that affects the lower leaves is usualy not as derious as one that affects the tops. It would be nice if you can correct it but I dont think it will fubar your crop.

From the pics you posted shows clearly a nitrogen problem....... nitrogen depending in how soulibe form it is and how fast releasing, they can show show either yellowing leaves or splotches the whole leave does not have to yellow it can have yellow spotting.....
The problem is you having more than one plant per pot; I know you said you were not having trouble with them;p but you are growing out multiple strains; do you have multiple strains in the same pot?
Like the problem plant in a pot with the rest that is not having problems? Things don't get better overnight with soil growing; it can take up to a week to show improvements.

hey stitch thanks for all your input. heres some pics a couple days after i flushed em with r o water it wasnt a heavy duty flush maybe more like a rinse
and not every plant recieved a flush just the most affected plants.
here is one of the healthiest plants in the garden single primo in 3 gal

Ya the one that is in the middle pic... that needs some nitrogen.....aretheydoing better after the flush?
Ya, go ahead and foliar feed with some nitrogen; cause the yellowing will progress and you still have flowering time, you want to keep as many fan leaves as possible; so for now foliar feed them and then when it comes time to feed them, give them nitrogen in with your bloom ferts
Thanks stitch also if you look at the first pic in this thread you can see a couple plants with the top leaves curled. a few of the plants are curling pretty severly im thinking that maybe my ph was a touch low i usually give 6.1 .6.2 the run off was at 6.0 is that too low for soilless and the cause of that leaf curl or possibly another deffieciency.?

yo johnny stitch helped me out with this one...my plants got the "the claw" and i found it was actually moisture stress i just backed off the watering and foiler feeding and they snapped back
but stitch is the man with the plan so see what he says
