Cannabis Troubleshooting

Hi Guys, In the last few weeks of constant rainfall here on the north coast I have noticed the humidty in my grow room climb from 60% to 80% and now I am starting to get mould in my grow room in the walls. I am saving up madly for a new centrifugal fan in the hope that better air flow will sort out the problem and I have a pedestal fan blowing over my plants at the moment but I cant seem to reduce the humidty ....have also decreased the watering schedule as well down to a bare minimum. Does anyone know any good methods to reduce humidity? maybe some of our friends up north in tropical Queensland or NT? I have heard that if you put a bowl of baking soda on the ground i…

*** Why not to use bug bombs *** Bug bombs are some times used by cannabis growers to get rid of various infestations. They should not be - full stop Why? Even if you believe with all your heart and mind that chemical companies never lie to us and that they are safe when used as directed (check on how Michael J Fox got his parkensons disease) they are not intended for use on anything that is to be put into the human body. Spraying bug bomb poisons on your cannabis and then smoking it is very very bad for you. People should not inhale burning pesticide or eat it either. In point of fact, the instructions on bug bombs (and other pesticides) say very plainly not to …

I have a problem with my jack herer and Euforia both are turning a pale green colour and curling under slightly, my room temps and humidity are near on perfect during lights on and off, all my nutes are mixed to a 2.0 EC as reconmended by lable for grow 20ml A and B per 5 litres i have recently smashed my digital PH tester i have another one on the way, would this be my problems to high or to low PH?. i also am running one 600hps light with two UFO LED lights i wouldnt think it was over lighting, as the plants were fine the first three weeks

Hey Guys, I have three Kali Mists in a small growroom in a recirculating Bubbler system. Since the beggining, one of the plants showed a slower development and stained leaves. I quit trying to address the "problem" and accepted the idea that it could be a genetic issue with this particular plant. I´m saying this because I tryed almost everything and the three are sharing very similar situations: - same nutrients for all, as individual buckets are connected to the same central control-bucket; - same light - a 600w HPS bulb hanging without reflector in the middle of them; - same air circulation - I have already change their places with no noticeable effects. Kali Mi…

this is my first grow so im really unsure of what to expect, im growing in a 1.4mx1.4mx2m mylar tent using a 600w hps my grow medium is 60/40 coco/perlite using half nutes at this stage as for ventilation i have 1 in 1 out both are 150mm ezi-fans. I set my tent up sunday and moved 4 seedlings into my tent, after about 3 days my first plant started to yellow and wilt on the under leaves, after searching around the forum ive just come to assume that its normal for them to shrivel. my second plant however is begining to yellow at the top of the plant here are some pics.. im not certain but from what ive read i think i may have over watered it? anyway any help would b…

Hey guys, I've just started growing, and have run into a bit of trouble! I had these plants sitting in a pot outside since about December, they were fine. Last week I knocked up a grow box in an old freezer, and stuck the plants under a 250W HPS inside. See here for what I have built.. maybe you can see some problems with my box? The plants were already flowering while outside, although they hadn't grown or changed much for a few weeks. I have since put them under 24 hours of light, could this be the issue? Temps have been between 25-30 degrees inside, i think this is okay? I am watering the plants whenever they look a bit dry, usually twice a day, until i see a…

High guy, despite having a odor sock my plants are getting very stinky, I am trying to upgrade my fan right now but in the meantime I want to buy a ionizer to reduce smell, does anyone know where I can purchase one?

any tips for salt buildup on the top of expanded clay flood and drain water flushing from the top is a bit difficult in this setup should I be concerned or is there anything to do to minimise/control it ?

hey guys, here's the pics. they grew up in jiffy pots and were replanted 5 days ago? the jiffy's were soaked originally in half strength veg nutes, the coco they were transplanted into was soaked in full strength veg nutes and i started on full strength nutes straight away after transplanting. the yellowing leaf symptoms of the main plant shown in the pics started in the jiffy pot (they only got rhizotonic at full strength for seedlings). they are growing rapidly, but i'm worried about the particular one i took pics of.. i took a picture of all of them to show the one on the right side of the pic - the very tips of the leaves are curled down and yellow - is this over f…
