Or as it's more generic name "Hemp Streak Virus". I have found after searching one text and a dozen sites what has spread throughout ALL of my mum's. I know it's has a insect vector (the fly's again) and it's has wiped out crops since the 40's. But how do I save my mum's? Treatment is always mysteriously never mentioned. Is it like HIV and no cure? I have pruned all the sick new growth and have started them on PH neutral with Rizatonic, Bio-Bugs. Last week they have been Bio-Buged with a drop of Superthrive in the PH neutral and the virus spread throughout every plant. If there's no improvement over the next week I will have to kill them all. Hoping it's not to late alr…

G'day guys. This is one of two plants planted late (feb) and grown outside. It was well into flowering outside but shithouse weather had buds spindly and far apart. I bought a 400w hps and moved them inside and set the light period to correspond with sunrise and sunset less about one hour. The other plant was more advanced, already producing resin and I harvested it after a couple of weeks. This plant was not frosting but thickened up nicely with good colas. It has been inside for 6-8 weeks now and is still not producing decent trichomes, and has started producing new growth and flowers from the top of most main stems. Have I stuffed up with giving it too much light c…

Hi there, I have some small brown spots about the size of a pinhead on some of the lower growth on only 1 of my girls. Plants are in 50/50 potting mix/perlite & have been supplemented with hydro veg nutes. Plants are growing horizontally. The spots have appeared in the last 48 - 72hrs on the lower areas of the secondary growth. This secondary growth has just recently started to fill out as Ive switched to 12/12 about a week ago. Im still using veg nutes(waiting for payday!!) I have checked closely with a 6x magnifier & there are no pests on underside of leaves or elsewhere. I have also read some nutrient defiency info on this site & others. Accordi…

HELP! I need to know if i am doing something wrong. Checked my plants and it is healthy looking,except fpr the tips of the leaves are turning brown and the leaf eventually dies. I have not been using fertilsers as i noticed this about a week ago and am just giving rain water at the moment. I raised the light up another 10cm's as i think the curling may be heat related(?). Any information will be greatly appreciated. Thanks.

Well this is my first grow, the plant is under a 250w cf so i know not to expect much, but it seems my plant is stugling more then i thought. Im not sure whats causing this. the plant looks like its dieing but strugling to stay alive. its 3 weeks of growth from a seed. leaves look droopy, colour seems ok but tips of the older leafs are browning. i water the plant with setlled tap water and a very small proportion of thrive in the water. im watering maybe every 4 days, the soil seems to be holding water well so any more then 4 days would be drowning the thing. ive got a small fan in the box rotating the air around, the temp is sitting on 24 degrees but im unsure about …
