Help Diagnose Small Spots

Not sure what this is, maybe potassium deficiency? Have checked with 30x scope and haven't seen any beasties.

other info:
strain - Blue God.
soil - Promix - BX
water/feed - once a week or until top two inches of soil dries (finger test for moisture)
Age - about 6th week into veg after initial 3 weeks of seedling stage. 9 weeks since seed.
light - 10 - 4' flouros (plenty of light for veg) on 18/6 schedule.
Using a product called Optimum for feeding. a two part formula part A has n/p/k of 5-0-2 and part B has 1-5-8. Ph balance with ph down to 5.8 when feeding.

This is only showing on the middle plant so far, the others seem healthy.


Any help appreciated.

what kind of food are you using?

And when using promix you wanna add dolomite lime to it because eventually your ph will drop when the peat starts to break down and make the soil acidic.

For the most part they look really good

Thanks Max. I''l be doing a transplant in the very near future and will add to the promix. The veg feed is a product called Optimum. http://www.optimum-hydroponix.com/english/html_en/main.html

Do you think the spot might be Potassium def?

are you using both parts?

ya both parts, but thinking up bumping up part B for more potassium

I would try that to see if it works, that should do the trick.. are you measuring your ppm's or just going by the directions?

been doing the feed directions so far, equal parts A & B. thee ppm usually comes back around 1300 to 1400.

After doing a little digging I would agree with your diagnosis

other than you slight issue those ladies look fabulous... beefy as hell, should produce a good yield

Thanks Max. will keep ya posted. the strain is supposed to yield some beefy dense nugs so we'll see.
