Cannabis Troubleshooting

I have two seeds from known source that I germinated in paper towels. I then placed them in rock wool, just gently below the surface. Root pointing down - water used was ph adjusted - in plastic starter tray with lid. Tray is on a warmer - ph 5.7 - temp 26degrees - light is brand new compact fluro. 14 days have passed with no sprouting..? I placed a small piece of vermiculite over the seed 'hole' after the first week just in case the light was the issue. I have no idea what could be wrong - any tips would be appreciated.

Hey all, Anyone used these before? Looking to invest in some insect predators to clean out some aphids. Last year I tried lady bugs and predator mites which pretty much died within a few weeks.

Something has been eating my leaves... Can't find any insects around but found what looks like eggs/larva on the underside of some leaves. Please help me diagnose my problem! Thanks Tmer

Hello people, anyways I got 2 plants off my uncle about 3 days ago didn't look like there was an issue with them but since yesterday the leaves on 1 plant have gone crispy brown the other 1 seems to be slowly getting a couple of brown spots here and there but nothing to concerning just yet. As for the soil I believe its half decent stuff, for the nutes he was using thrive. outdoor plants btw. Here's some pics. I live in Perth and where currently experiencing a heat wave so possible under watering maybe?

Hey, I've got an auto star ryder and a "the ultimate" under CFL's in a cabinet. They spent their first 5 weeks or so outside in the rain and I noticed these flies (I think they're "Dolichopodid Flies") on them occasionally & wasn't too concerned. Once I put them in the cabinet the fly population seemed to increase dramatically. The other day I noticed the same white spots appearing which I got on my last grow due to spider mites. I used the same formula (which worked last time) it seems to be killing the flys off faster but the white spots are increasing aswell as some yellow spots and holes. I've read these flies feed on aphids and other pests, could they maybe o…
