I have 4 seedlings growing germinated around 12/11 they are looking very healthy but some sort of bug is eating them. 2 of the seeds i germinated were eaten just as they hit the surface and the round leaves on the 4 remaining are being chomped on, one of the leaves is almost torn in half. they have already developed their 1st set of true leaves and these havnt been touched by the bugs. what is this? slugs?

hey to all ozstoners... this problems seems to hit after about 14 days of 12/12 light and gets worse fast which stunts growth, i'm growing some in perlite and some in rockwool which all are doing it. The ph is around 5.3 - 5.8, i'm using canna nutes in a run to waste setup humidity is low and temp is just right. the problem has just started after 12 years of successful growing and has wiped out 4 harvests now, the only thing i have changed was my address. my old house was on rain water and so is this house.

I just noticed I have about 50 tiny tiny black (white when in black tray) little bugs that like to swim and jump around in the water. They are too small to take a picture so I put them under the microscope and drew a picture. Any idea? What should I do? I have already cleaned the system with bleach water and have fly traps.

Hey people im new here and pretty new to growing. I have come into what mostly likely is a noob problem. I know what I did wrong and have learnt from my mistake. I brought in these clones from somewhere else and they have carried red spider mites in with them I didnt spray them the first week because I thought it might hurt them. It is now the third week I probably noticed them to late but I have been spraying them every 3 days and trying to keep the plants themselves and the room air moist. Are there any other things I should be doing? Your help in this matter would be much appreciated.

Found the first one chillin on my plant (outdoory), and the second while trimming. They don't seem to have done much damage if any. I've never seen them before and I'm just curious as to whether anyone knows what they are? Cheers

So some of you know of my rockwool clones trials and tribulations. Well just when i though everything was ok, i found some dark matter in my rockwool tonight. At first it looks like some kind of dark mold with dark droplets of something, really small dots. But as i ripped a few open, i found what looked like insect parts. Looked like a miniature scorpion tail, and various ones had different small parts in them. I can only assume maybe some kind of eggs? Should i just toss the batch? Should i ride it out? Anyone ever had this...

Hi everyone, trying to get rid of scarid fly, fly spray works fine for the ones flying in the room, but I need to get to the undeveloped ones in my root zone as this is third crop that has them. Hydroshop gave me Scarid 10 which is a Group 3 Insecticide it has 10g/L Deltamethrin. The hydro guy is not good with advice etc, I only go there when I am desperate, so I don't trust his advice that it can be added to the tank unless someone else can back it up. Does anyone know if it is ok to add to tank and at what rate per litre? The directions on the bottle are all for spraying, not adding to the tank. Thanks aussie 1
