Week 7:  SPIDER MITE ATTACK!!!  (But otherwise healthy)

Strains in the tents:  Russian Doll, Sour Key OG, and Pineapple Express (scroll down for details by strain).

Grow method:  Indoor SCROG (although the screen is not on yet) with LED.

LED Details:  2x California Lightworks 1100 + 2x California Lightworks 550, on our VEG A setting of 50: Red, 99 White, 99 Blue for 20 hours.

Gear we are using:  Pure Tents, California Lightworks 1100s and 550s LEDs and controller, Pure Pots (10 gallon), Promix HP, Dollar Store EZ Pods, Green House Powder Feed, BlueSky Organics Organic Reactor, Safer's End All miticide concentrate (plus water and a spray bottle), microscope.

This week was eventful!  First, we moved the healthy God's Pussy to a separate room and divided the rest of the plants into the scrogging tents (Sour Key OG is in 2 separate tents).  While we were going through our garden, we noticed some weird white spots on leaves on a couple plants.  As indoor, soil, from seed growers, we rarely have this issue but it hit us:  The dreaded spider mite!  Where did they come from?  No idea.  We were trimming in an outdoor garden the week before, maybe they came in on one of us?  Maybe a dog brought it in?  Mite fairy?

 

Either way, we caught it early because we check the plants closely every day, which is super good news because its totally treatable!  Learn more about catching spider mites early and treating them.  We are going to keep all the plants in veg until this is resolved.  We don't even want to add a scrogging net to the tent until this is fully resolved (even though they could probably use it now).  Our net will just be a little higher than we expected.  Another great thing about scrogging is we have fewer plants overall that we need to treat.  We can give each plant heavy focus and make sure they are fully covered.

Strain name:  Sour Key OG
Genetics:  Amnesia Haze X (Super Lemon Haze X OG Kush)
Flowering time:  8-9 weeks
Yield:  Heavy
Level of difficulty:  Medium
Notes:  These were the first plants that I noticed the spider mites on.  To the naked eye you might not notice anything without looking very closely.  In fact, even when the affected leaves are in your hands you still might not see anything without a microscope.  But they are there!  So we did a spray with our miticide concentrate making sure we focus on the top and bottom of leaves.  Because we had 2 more vigorous phenos (larger plants) and 2 slightly slower growing phenos (smaller plants), we mix and matched so the tents will fill at around the same time.  You can really see that most to have hybrid leaf appearances while the left plant in Sour Key OG 2 tent seems to have more of an indica leaf appearance.  We'll see how this one develops!

Strain name:  Pineapple Express
Genetics:  Big Bud X Skunk
Flowering time:  8 weeks
Yield:  Heavy
Level of difficulty:  Easy
Notes: You can't see them really, but here we are, the plants with the worst mite infestation so far.  Some leaves had 2 or 3 little critters on them (which is very low--they multiply to hundreds in days--so we caught them very very early).  The worst of the 3 plants is probably the middle one, so we focused a lot of the miticide concentrate on that one.  Everything gets sprayed to be sure, because if one has them, they all do.  This grow room is pretty small.
 
Genetics:  Kuban Sativa x Northern Lights x AK-47
Flowering time:  8-9 weeks
Yield:  Medium
Level of difficulty:  Easy
Notes:  My favourite plant to grow also got a couple nips in the leaves so we treated them all to be sure.  One of the 3 is growing a little faster than the other two but all still pretty uniform (as always).

Hi Guys,
Glad you caught them early! Just be aware that using any miticide that contains pyrethrin causes spider mites to lay eggs as a defense. In temperatures above 75 degrees that means they can breed every 4 days. Keep checking the plants every 3-4 days and switch up the treatments as they also become immune to pesticides. Drugstore strength Hydrogen Peroxide of 3-5% can also be sprayed on plants in vegetative state without any harm, but will kill bugs.
Cold water is another treatment that they do not like. Cover the soil with a bag or a piece of cardboard with a slit cut into it to cover the top of the pot (this will keep them out of the soil) and put them into the shower and rinse them off. This does not kill them, but causes them to fall off and be rinsed down the drain.
Also, spider mites are the only pest that makes those white speckles on the leaves as if they were caught in the mist of a white spray can.
Never bring any plant inside from outside without treatment first as it will have bugs and yes change your clothes and wash after being outside near any plants before handling or visiting your garden.
Good Luck and keep up the good work!
Deb
