First time grower -- spider mites during flowering

Greetings! I'm a first time grower, almost 4 weeks into 12-12 light cycle on a 4 month old Super Silver Haze mother plant. She's getting a 1/3 dose of Hygrozyme and Botanicare Flower Power 2-2-5 Bloom food twice a week, which is every watering. The temperature stays between 72-81F, and humidity is 25-45%. The plant is in a reflective cabinet that's left open while lit to allow air circulation from the cracked open bedroom window, then sealed when the lights go out. She is lit by four T5 CFLs (2 blue 2 red) and a Sunshine Systems GlowPanel LED panel.

She shares the grow space with several clones at various stages of their veg cycle. The two big ones with fat leaves are a local breeder's creation, Black Betty. The ones with the narrow leaves are Skunky Haze (or Hazy Skunk, I can't ever remember which way it goes -- yay dyslexia!), and there are a couple of young SSH clones taken from the mother plant before starting 12-12. Most of them were cut 5 weeks ago. They are being lit by the higher-powered GlowPanel45 LED panel.

I have a couple of questions. First, how does Hazel (the flowering SSH) look? Since she served a long life as a mother plant before inducing flowering, she has tons of tops, and is very bushy. I plan on staking her tomorrow to help support the taller stalks.

Second, I included a shot of my grow room to show how the veg plants are located in relation to Hazel. This morning, I found signs of spider mites on one of the Skunky Haze plants, and on closer inspection, found some on the larger Black Betty too; the other plants don't have any signs of infection yet, but I have no illusions that they're free of the Borg invasion. I've treated all of the veg plants by spraying with a solution of 7.5ml neem oil - 7.5ml pure dishwashing soap - 1 liter water, and plan on re-treating every 3 days until signs of mites are gone. Due to the layout of my living space, I don't have the option of moving Hazel out of the room with the veggers. Since I'm a mere 3-5 weeks from harvest, should I treat Hazel with neem, or with something else? Does anyone have any other advice, either to protect Hazel's harvest or to protect the other plants? I'm willing to lose the veggers if need be, but Black Betty was created by a local connoiseur, is astonishingly good quality smoke -- way beyond anything I've ever tried before -- and will be impossible to replace.

Thank you for your advice!
:peace:

open doors = bugs walk right in
 
you have some nice and frosty bud there, your doing good job
 
Excellent, thank you for the feedback!
And thank you Joe for the great link! :nicethread:

I'll post more pictures as the grow progresses. :popcorn:
:peace:
 
Good stuff, thanks again!

I've purchased a Hot Shot No Pest Strip, placed it among the veg plants, closed the room and turned off air circulation. I'll open things up again tomorrow. In the meantime, I'm also blasting the leaf bottoms with plain water and inspecting manually.

I'm keeping the environment such that the flowering plant is happy (around 75 degrees and low humidity), but can easily shift that to colder and more humid... I'm just worried about bud mold on Hazel if I try to make the spider mites on the veg plants more unhappy. What are your thoughts on this balancing act?

Thanks again for the suggestions and links!
:thanks:
 
Give it a go and see what happens... If your first treatment doesn't cure the problem then formulate a plan as a new line of attack.. I have been battling with a fungus gnat problem and some of the "cures" (especially from garden centers) were useless.. Listen to the advice of the guys on this message board who have battled spider mites as opposed to some "retail" specialist... I have found the help from the local gardening center experts have only costed me money and not cured the problem.
 
Day 3: Blasted leaf bottoms with plain water. No signs of spider mites visible to the naked eye.

Day 4: I've staked the flowering plant to support her stalks that are rapidly getting heavier, and have been spraying her lower, non-flowering parts with the neem/dish soap/water mix, as well as misting her soil. All of the veg growth plants were hit a second time with the neem mix as well, on all surfaces and the soil. I also trimmed all lower leaves (the ones I couldn't ensure had been coated with neem) off the veg plants.

Using a 60x microscope, I inspected the leaves trimmed from all of the plants. The ones that hadn't shown any sign of infection still look fine (yay!). Examining leaves trimmed from both of the plants that had shown spider mite infection signs, I was able to spot a few of the translucent eggs, but no adults.

The plan: I will continue blasting leaf undersides with plain water on days 5 and 6, and will do another round of neem on day 7, day 10, day 13, and day 16. This should take me through three mite breeding cycles, and will hopefully be enough to eliminate all of the stragglers. Once I'm free of signs of spider mites, I'll keep using the neem mix once every week as a preventative measure (since I have no way of circulating air other than using an open window).

I'll post another update when I have news. Also, since the flowering plant is within 2-4 weeks of harvest, I'll post photos of her as she matures. Thank you all for your support!
 
Thanks War -- I do have a Hot Shot no pest strip placed amongst the vegetative plants. I've been keeping to the schedule of spraying with a neem-soap-water mix every three days, and spraying leaf undersides with plain water on the off days. My last "intensive" neem application will be this Friday, at which point I'll scale back the neem applications to one per week, just to prevent recurrence.

The plants all look great, and there haven't been any signs of mites or their eggs since spotting a few eggs on day 4 (I'm now on day 13 of the spider mite invasion). Hopefully I've tackled the little buggers! :phew:

Here's a couple of recent shots of the flowering plant. This coming Sunday marks six weeks since changing her to 12-12, so it's almost time to start looking real hard at those trichs to determine harvest time! Super Silver Haze usually has a 10-11 week flowering period according to what I've seen online so I probably have another month or so to go, but the wait is almost over! Good thing too, since the smell is getting pretty strong, and it's sooo tempting to nip off a small lower flower "just to see what it's like"...! :dreamy:
