sorry about the lousy pics but it's as good as I could get. Under a microscope I can see bugs on the underside of leaves I recognise but forget the name of. So far I can't see any movement under what looks like a scab held a small distance off the leaf. The critter builds this 'roof' it lives under, possibly out of excrement. The larger, so far, are visible with my lousy eyes, the smaller only just so but a decent set of peepers would probably say otherwise. I'm actually suprised because if they are what I think they are the 'pest oil' I recently used chasing out the last lot of uninvited guests is expected to effect them. TIA

some of the new growth in my plants have brown soft leaves so i investigated a little and noticed tiny caterpillar/larve, they are no more than 5mm long and you gota pry open the new leaves to see them, I was wondering if tomato dust will kill them? just yesterday i sprayed the plants with eco-neem to get rid of any bugs and leaf eaters, will tomato dust do any good? I know i can get yates caterpillar killer but other than that is my only alternative to chop the new growth at the tips just under the leaf cluster? I dont mind as long as it doesn't have a big impact when flowering starts.

Hey guys, I think my girls are about 1 week from harvest (this is my first crop). I have two plants in a run to waste system (their some afghan strain) growing in coco/perlite approx 50/50 Under a 600w HPS They get watered for 4 minutes every 2 hours the light is on Used Canna Vega/Flores A+B through out and PK for a week a few weeks ago I had scarid flies, wouldnt say an infestation just half a dozen or so visible adults at any one time (god knows what was happening under the surface though).

All of a sudden (after a number of years), the (flowering) fan leaves would start showing brown spots, of which would progress and brown out (kill) the fan leaves. Starting at the top going down the plant Each plant would not die, but would not progress beyond week three. Multiple strains (of proven output) affected Ph is 6-6.5 ppm ranges from 800-1200 (city) water has been tested by chem lab and checks out ok Multiple version of food: (Tiger Bloom w/bloom builder, CalMag addition, Dutch Master Gold) Folier spray application to leaves accelerated the detoriation process by a factor of 2x Hydro/rockwool basis feedings range from 1-3 minutes every two hours Temp is 80-85 …

my first post, so hi all! i'm doing my first attempt with 3 exterior plants. I planted the seeds already late (7 July, spain) but till now just water them, and gave the nutrients. I changed to the blossoming nutrient 2 weeks ago. I was noticing that the bottom leaves where having a problem, some getting yellow too soon and dying. They start to have this brown spots from the steam to the leave, looks like rust, and then they die. Last week I went to the store where I bought all the stuff but they where closed to holidays, so I'm having a hard time seeing the plants dying slowly I attach a picture os a leave, this one is already on the top of the plant... really don't…

while repotting today I came across this mother. I don't mind bugs in m' soil, proves the soil is good. I have more of a problem if the bugs move out (shows shitty soil). I suspect however that this guy may be a root gobbler, which is pushing a friendship WAY beyond its limits. anyone know what it is? (sitting in the bottom of a 7oz glass) TIA
