Sudden White Spots on Random Places - Please help

[tempes~tos]

Hey guys,
I have a grow going with 5 Subcool Querkle, 2 RedLazerLite, and 3 GHS (Fem) King's Kush.
Today I found out that 4 of my Querkles are MALE.

So I am left with only 1 female And now I see, that just since yesterday, she has developed all these weird spots! She is the only plant affected in the tent.

They have been in 12/12 for 3 days. Prior, they were in 18/6 for 3 weeks.

Soil: Roots Organic
Food: FoxFarm GrowBig, FoxFarm "Kelp Me Kelp You", Earth Juice Cal-N-Mag
Ph: 6.3-6.5 (nute solution)
PPM: 115-180 (nute solution)
Tent: 4x2x5
Light: 1020w COB / LED (680w actual draw)

This is the plant. She was perfectly healthy, for the most part, until yesterday.


Then these spots appeared:




Any help would be very much appreciated.
Shes my only girl

Getting Worse

Getting Worse

If anyone could chime in, would be really cool.
All the other plants are fine so I can't figure out whats wrong with this Querkle.
Today the spots are worse:

As you can see, the other plants seem to be fine, and all got the same exact treatment.

Could be a fungus in the plant brought on by gnats. Watch close for gnats. If it is that, it could spread.

emeraldcityog,
thanks for the reply!
could be. i have some sticky traps and they have been catching some small black gnats.
I notice the occasional gnat flying in the tent.
I will research how to treat for these, but do you have any tips on getting rid of them?
Thanks

Grow it out, she'll be fine. Could be pH out of whack maybe.

Hi Bobbo,
Thanks for your reply.
I have come to the conclusion that I actually have root aphids because its getting worse, to the point I now have necrosis on some leaves. She is still the only plant affected however.
No new growth at all.
Last night I did a soil drench with SNS-203, a pesticide containing clove oil, rosemary oil, etc.
Today I will transplant to cloth pots. Hoping the air pruning will prevent re-infestation.
I will update on the progress.

If it has root aphids better get some acephate 97up and riptide before you get to far into flower
2 grams acephate 2.5 ml riptide into 1 gallon water ph to 7.0 dunk root ball for 20 mins.

After the dunk wash off root ball. And don't put plant directly under light or raise lights high.

All the best brother, hope you get them straightened out.

Thanks guys.
So far, the SNS-203 has worked really well.
Before the drench, when I grabbed a handful of the soil from the top of the pot she was in, i could see the little fuckers crawling around, and kinda jumping, like fleas. little white bugs, tiny.
After a single drench, nothing moving at all.
I transplanted her into a 7 gallon cloth pot, and now, 3 days later, she is recovering nicely.
I can see the life growing back into her, so I'm very happy.
From now on, I will be using ONLY cloth pots. The air pruning makes them a lot less susceptible to root aphids, gnats, and fungus.
