Yellow Specks with complicated situation.

Alright, I basically know what's going on but I need some advice on how you guys would go about fixing the problem.

I have a plant 73 days since germination (started from a bag seed) and I royally screwed the pooch.

I have some pictures below showing some yellow speckles on my leaves. It's only affecting the leaves up until about halfway up the plant, however they are on the rise. The lower leaves also seem very papery and are probably going to die soon if I just leave everything the way it is. The top most leaves seem to be nice and plump and healthy.

I'm almost positive its some sort of nutrient lockout. About two weeks ago, I had a stupid moment where I was mixing my fertilizer water and I was so tired I didn't realize I messed up my calculations and made the solution almost 2500 ppm strong! I watered my plant with it twice before realizing my mistake. I flushed with water, and transplanted into a bigger pot, but I'm almost positive it's in nutrient lockout and isn't able to take up water or nutrients like it should be. The pot is remaining far too moist for a healthy plant to be taking up a normal amount of water. It's borderline saturated with water for good number of days now, and the lower limbs are very droopy. I think the moisture control potting soil I used is retaining far too much water for it to properly drain which has made flushing very difficult without suffocating the plant.

Everything else seems to be in balance, I have a soil pH of 6.7, and the temperature never goes outside of a 76 day high and 71 night low.

My question is, do you agree with my assumption of what is happening? How would you go about fixing this if you were in my situation? I realize I need to flush to get the salt content down so the roots can absorb more moisture, but it's already VERY wet and I don't want to suffocate the plant with over watering. What do you fellas think?


Pictures:

First two are of the yellow specs plaguing the lower half of the plant, last picture is of a perfectly lively seeming top portion.

Check the underside of the affected leaves for bugs, more specifically spider mites. Use a magnifying glass as they can be very hard to see with the naked eye....

Little spots always say bugs to me. Just a starting point.

Not spider mites... I think it will be ok...... Moisture control soil releases more nutes if you get it really wet.

Yeah, I scoured the plant for bugs, scouring a couple of the leaves with my microscope to make sure I wasn't missing anything with my naked eye. One question tho, should I give it a series of good flushings to try and dilute some of those nutes or just continue to water with regular water?

You better look closer because those spots are most certainly from mites. Only takes one or two per leaf to cause that many spots.

well if your 100 percent positive its not insects being spidermite then obviously its a def i would seriously give them a good shot of food looks to me like mag def there hungry get your ph in order cause i bet its out to lunch flush with a mild food 3 times pot size making sure your readings of ph are the same as whats going in

Its definitely not mites, I looked at a bunch of leaves under the microscope and took white paper and put underneath the leaves, shook them pretty good, and still no signs of bugs.

I flushed the put with a bunch of water. The pH of the runoff was 6.7 and the ppm was almost 1200. It had to be nute lockout combined with dehydration sure to the high salt content. I'll flush it again later on to dilute the soil nute content again, wait a couple days then get back on to a normal nute regiment.

I can't believe I mixed the nutes so strong when I started this whole problem.

yup get your ppm to 700 and start from there but flush with light dosage of nutes till runoff is 700 ppm try to maintain 6.8 to 7.0 ph nuetral

Interesting I found this post so quickly.. I am having the same problem (so don't feel alone) . Mine started about 10 days after transplant from veg box to bigger pots, and under a 600w. I am pretty sure it was because of the soil I used.. (some really good soil, mixed with some cheap potting soil, and a bag of manure) a few plants are not responding well. I grabbed a soil PH meter, and my soil was reading right where it should be. I added a bit of dolomite lime to the soil as a buffer (because my soil had none) and I will mix up some with water to spray on the leaves later, just in case its a cal Def.I re potted with some new soil that I know is better than what I used (probably went overboard here) then noticed that my pot drainage trays suck, and my Potts were sitting in the run off. I threw a few 2 inch blocks under each pot, to get them up a bit. I will let you know in a few days if any of this stuff has helped.

Took these pics about an hour ago. Took a pic of the underside of one of the leaves, to show its not mites. You can see a few little dark spots in the pic, but it was dirt from the transplant, and wiped off.

I wouldnt spray your plants with a lime solution. The calcium and magnesium dolomite contains is not really water soluble. It takes 2 to 3 weeks once mixed with the soil before the buffering and nutrient benefits start to really come into play.
