i flushed just over a week ago, problem persists.
my nuits are iguana juice, i use double the reccomended dosage. - Is it possible to over fert with organic nuits? ive read no, but i see evidence.
plants seem stunted, they are about 1.5 months old.
some are tied down.
temp ranges from 76-82, lights on 24/7.
im runnin a 200watt cfl - my first cfl grow
will provide more details just ask.
PLS HELP! i thought i had green thumbs up until this indoor garden.

P.S. the bottom plant in the first pic is a different plant and i just misted diluted IJ on the plants, thats what the white spots are on the leaves

GL??
i will consider iron and see what i can do. thanks for your imput.
i thought it may be Mg.

the plants have had this problem for a while, since their first to second week of veg. alot of leaves have been lost.
recently its been spreading faster.

the yellowing started at the bottom pair of fan leaves, and moves upward attacking the next oldest set of fan leaves.
note it varies per plant.

should i use epsom salt in all future waterings?

would the normal dosage of epsom salts diluted in water cause a build up of Mg if i never had a Mg deficiency in the first place?

so many questions, im just feeliin a little panicked

From your first photo I am sure light density is a problem. You need several more bulbs spreading light over the plant canopy. That means at least double or triple the Watts you have now. The lamps must be within a couple inches of the tops.

If light density is inadequate, nutrients will burn the plants, and plant performance will be poor. Light density controls nutrient absorbtion.

I woud try a spray of cal-mag for 2 days and see what happens?
then if gets better just a bit in water solution..
sounds like more light is needed get a 250w hps... or bigger..

I am using 1700 watts equivalent on 12 plants.. its not actual 1700 watts, much less, but still about 140 watts per plant. (6500k household cfl's, 17 @ 100w equivalent each) your plants are much bigger than mine also, mine are maybe 10 inch tall max, and in hydro. point being that you need alot more lights and alot closer, my lights are 3 inches off the tops.

Frankly, with as little light as you have provided, I am amazed those plants look half that nice. You may have a nutreint problem, but no one can tell for sure untill you have more Wattage over the tops of those plants a few days.

I'm curious to what your problem is because I'm having a similar problem with just a select few plants we have. Brown spots and yellowing of the leaves with green veins. I have been using epsom salts regularly so I know it's not that. I have been giving enough ferts, so maybe its over fert. The only thing I'm not sure on is the water and PH of the water. We went and got a bunch of distilled water and are going to use only it for now on with no addatives to see if there is a difference.

And it's not the light, we have coverage over all of our plants with about 400w of cfl's and 80w of led's so I know that is not your problem. Let me know if you see any improvement.

Distilled water is ph 7.0. You need about 6.0. That will cause a big problem with some strains.

I'm just now about to start using distilled water, so it couldn't be the problem because we havn't used it yet, and we were PH'ing the tap water to low 6's. So the problem started showing while using PH'ed tap water. Our distilled water from Kroger is measuring around 6.5.

i plan on switching to distilled tommorow.
ill buy a PPM and/or EC meters. problems solved.
im also using tarantula.
my soil is 1/3 worm castings.
i bred these strains myself.
and oh baby these thumbs are green, its my water that must be yellow ;)
good luck nroth. your plants look strong. Stretched, but Strong.

Maybe ill just fire up one of the ol' 1000 hps.

looks like it might be your pots. the roots might be getting pot bound. transplant them into a bigger container. 1 gallon of soil for every month the plant is alive. Normal buckets do a good job, cheap, black and 3 gallons. Just make some drainage holes. I have 4 plants in 4 buckets atm. If not that the its most likey nitrogen or PH, get ur PH to 6.5
