purple kush problem (w/pic)

[fatal1]

(Disclaimer.... I'm not here to debate if this is "real" PK (purple kush) or not. I really don't care. I only mentioned it because I'm not sure if my problem is strain related. If that's a problem I'll just call it MJ#1 )



A little history... I got this clone back in September from a great place in Van Nuys. I usually grow in coco but I wanted to make this PK a mother so I put it in a soil mix. The mix consisted of Miracle Grow Organic potting mix, blood meal, bone meal, perlite and peat moss. The only thing that I did not add was dolomite lime.......<big mistake..... This plant had never had nutes until day 14 flowering, just water. This plant grows super slow and only stretched a few inches. It starts flowering fast after the flip to 12/12. It has a strong odor in veg. I really want to save this plant. She has a place in my heart.

If flowering, when did you switch over to using Bloom nutrients? N/A
What order are you mixing your nutrients? (example: veg nutes 1st, bloom 2nd ect)
What is the TDS/EC/PPM of your nutrients used? about 250 ppm
What is the pH of the "RUN-OFF"? Not checked
What method of pH test was administered? Using Strips? pH pen? Hanna Combo Meter
How often are you watering? once every 3-4 days

Tell us about your ventilation, intake exhaust and when its running and not running ? 1 fan pulling fresh air in; 1 fan circulating air inside; 1 inline fan on cool tube;
Is the fan blowing directly at plants? over canopy
Is the grow substrate constantly wet or moist? moist now. I let it dry out a little
Is your water HARD or SOFT? Well water with a ppm of 89
What water are you using? Reverse Osmosis (RO)? Tap? Bottled? Well water? Distilled? Mineral Water? Well water
Are you using water from a water softener? N/A
Has plant been recently pruned, cloned or pinched? No
Have any pest chemicals been used? If so what and when? Neem oil at 3 week intervals. Organocide once before veg once before flower
Are plant's infected with pest's? No. I hope not!



If I need to add more pictures/information let me know.

Your metals are being locked out by your acid soil. It is a lucky thing you have bone meal in there; it is doing some of the job that the lime would have done and giving your plants the calcium they need.

I see you have not checked runoff pH so that is going to be a project. How long have they been in those pots? I hope they are ready for a re-pot because that is an option that will really help you.
Also I see your well water is at a very low ppm- that, combined with no lime, means you HAVE to add calmag up to 250ppm before adding your nutes.

If those plants are ready for transplant, I would do the following:
Get a pH testing /up/down liquid kit like the GH one.
Test your runoff pH.
Make up a flush solution that will counteract observed problems- for example, if your runoff is at like 6.0 and you want to hit 6.7, make up your flush solution at around 7.2 and gently pour it through your plant until the runoff reaches your target pH.
Then, make up a solution of tap water, calmag to 250ppm, adn then just your base nute (and micronute supplement if you need to run one with that system) mixed at 1/2 strength, pH to 6.8-7.0, and water with that.
Slice a few more holes in those grow bags too while you're at it so the soil dries out fast.
As soon as the soil is dry enough not to break apart if moved, get ready to re-pot into a larger pot that has plain potting soil such as promix (yay! lime!) with a bit of extra perlite added, and re-pot into that. Water lightly, just enough to settle the roots into their new home, and then go back to a normal feeding routine.

Also, if you have a micronute supplement available, do a light foliar feed with it to keep that metals problem from getting worse. If you don't, dissolve 1/2 teaspoon epsom salts in a quart spray bottle with 1 drop dish soap and use that to at least take care of the Mg problem.

just top dress with some lime and water it in well

That looks more to me like it's hungry for some iron/zinc, since you did not add lime and your water is soft your water is not carrying a lot of minerals to the plant and since you have only fed twice which is a good thing you only fed them twice, because MG organic is strong and since you added peat and bone/blood meal you would have easily burned them if you fed them regulerly, but since your water is soft you could have gotten some micronutrients to use with every watering, small amount of course.

From my view I don't see a problem with locking out I just see a deficiency based on 2 things, one the plant is showing no other signs of issues besides this one, the plant is otherwise green color is normal and no stress and no curled leaves or burnt tips.....

This to me is just a common micronutrient problem, you can solve this by adding lime to it next time. You need to get some micronutrients in them, something that has zinc/iron I can't tell which because the picture is too dark. iron and zinc can start alike, but zinc is more neon green where iron is a brighter green.

zinc affects the outter edges where iron affects the inner leaves.

Should I get the Cal-Mag Plus and a micronutrient? Or should I just add a little lime? I don't plan on using soil again and my coco plants look great.

A bottle of spray-n-grow is great to have around. You'll find yourself using it frequently.
I'd still get the calmag, and calmag is SUPER useful to coco growers, so you'll use that one in the future too.
