A)How bad was your infestation and what effects have you observed in your plants/grow?
I have had these guys for three cycles, but upgrades prior to the current cycle have taken average rh from <20% to 40% or so and I have seen a significant jump in population. Two or three "fliers" stuck to the buds have become dozens. I'm seeing a lot more crawlies on the leaves and containers as well.
The symptoms were very pronounced, and the infestation actually caused half my strains to hermie right after being moved to the flower room. That was the most disturbing symptom for me, and it is what triggered me finding this thread(which is honestly the best resource I have found regarding this god forbidden plague).
-Slight curling of some new leafy growth.
-Leaves turn from healthy green and glossy to a more dull green.
-Leaves may have tiny red or white specs or larger rusty spots on the leaf margins.
LATE SYMPTOMS(USUALLY AROUND DAY 25 FLOWER)
-Some larger fan leaves may develop rusty/off color or just plain sick looking patches and twist or curl and die.
-Bottom most fan leaves start turning yellow-ish usually fading to the veins like a mag deficiency.
-Yellowing works its way up the plant like a nitrogen deficiency.
-Plants look ready early
-Bud quality, size, maturity are lacking.
-Most heavily infested plants have used up all the green from almost everywhere on the leaves by harvest, even without a flush.
B)Have you grown the same way before with success or with the same problems? Have you grown a different way before with success or the same problems?
When I was working with a less humid room(15%rh), I was getting okay harvests of respectable quality, but the plants really prefer 40%rh to 15%rh so I tweaked my room... well the aphids went nuts; there are fliers stuck to buds, crawlers all over the leaves, and I assume plenty of larvae suckling on the roots.
These parasites have most certainly
been effecting pretty much everything about the final product. However, it seems like they prefer some strains to others for some reason... or maybe some strains are more resistant to the pathogens that are tryin to infect the open aphid bites. Since I was running multiple strains, I was still getting some real nice quality buds from the plants the aphids decided they didn't like.
C)Have you treated them before (if so, how and what were your results/conclusions)
I just treated them like a week ago after finding this thread. After a complete foliar spray and root drench with Spinosad, I am confident that Spinosad works to reduce numbers on the leaves, roots, and in the air... I plan on combining the Spinosad with Botanigard ES. Basically my plan is to make my containers a real hostile place for an insect to live; deadly fungus on the prowl in the coco, Spinosad clinging to the roots ready to poison any biters. God I hope this works...
EDIT: SPINOSAD IS NOT EFFECTIVE FOR APHIDS: I DO NOT RECOMMEND A SPINOSAD ROOT DRENCH.
D)What type of medium/nutrients and what type of setup (hand water, ebb/flow etc)
SoulSynthetic + Earthjuice nutrients
