Cannabis Troubleshooting

Ok, heres the problem! A few of my branches have started to dye off, only the smaller ones but its shitting me the leaves yellow and have sort of grey tips on the leaves, i think it might either bt over fertalizing or under? what yopu experts think? Its not the main branches i must had only the ones which seem to be little thin pricks.

I'm running a hydro setup indoors in soil. I got home from uni today and found some bubbly yellow growths coming out of the soil. Sort of looks like parmessan cheese. Anyone know what these are? are they bad? how to kill? etc

Aight my grow was goin great (first female AFTER MY FIRST 14 PLANTS WERE MALES) and now about 4 and half weeks into flowering alot of leaves r starting to turn yellow and some have brown dots on em. It's being grown in soil and I give it proper nutes and all. Anybody know the problem? I'll post pics in about a day or two

Hi, Although I dont have a grow myself. I am watching a friend grow his and learning all I can before I bite the bullet and start a grow. Now I checked on his grow this morning and found some weird shit, his top leafs are curling up bad almost looking like a tube kind of, it doesnt appear to be a nutrient problem as hes only running at approx 1.2 EC, and his Ph is 6.2, his nutes are well oxygenated by a airstone. It cant be heat as he actually overkills the ventilation with 2x 250mm hydroponic fans. The light is approx 2 feet away from the tips. heres a leaf-

Hiyas! ok i got a couple plants going outside but they are being eaten up a bit by what look like big grasshoppers and god knows what other weird queensland bugs (i just move to brissy from canberra...fuck the bugs are huge up here ). Can anyone help me with whats best to put on my plants to keep the bugs away, i want something safe and organic that wont fuck up the taste or anything. I had planned on smokin these buds so i dont want nasty chemicals in em. thanks, fnord

I bought an insect spray from woolies in the hope that it would rid my plants of the little green caterpillers i had been getting. I sprayed em last night, and today when I just checked em, the leaves are turning brown and drying out. It is a fucking hot day here today, but I would think that has fuck all to do with it. I have moved the pots into the laundry, out of the sun, and washed the plant down with fresh water. some of the leaves were so dry the just crackled in my hands. man i shoulda just gone to the garden centre and got some neem or biocide. I am a fucking retard! anyone had any experience with shit like this. the active ingredients in the spray were Pyrethr…

Hi, I have a 7 plants. they are approximately 2 mounts old. they are under 20+25W compact fluros for 24hour . they are in ~1m3 Aliminum veneered cardboard box. As you can see in photos, two of plants not growing good compared to others. But worse, all of my plants older leaves are get paled and dry. Used soil is bought from a market. (labeled as potting soil - torf) 1.5 week ago i started give liquid manure to them. (includes %20 N, %20 P, %20 K, etc.) I read some topics in forum and i find some points i can reform. but i'm not sure what must i do. please look my plants picture gallery and suggest a solution. thanks

Greetings. I have just noticed these little tiny caterpillars (about 3mm long) on the underside of my leaves. They appear to be making bits of the leaves go transparent/clear... See attached pic of what these little suckers look like. Any, preferably chemical free, ideas to get rid of them will be appreciated.

I have a few plants growing in pots outside. they are all about two weeks old and growing pretty strong. Yesterday when I check them, some of the leaves had a clear part on them ( sorry , best description I can think of) after checking under the leaves ( thanks WC) I found some little green caterpillers. I squashed all the ones I could find, but want a more permanent solution to this problem. I read in a previous post that someone had used a spray product called "NEEM". Can any one offer some advice on this situation many thanks

Firstly, I want to say hello, from the U.S.A. I have grown a couple successful plants, but lately I have had a problem. Here it goes: I have started four different crops within like the past 2-3 months. I have no problem germinating, or sprouting. That occurs without a hitch, but that is about the end of it. The plants don't even develop the first set of 3 bladed leaves. When they sprout they are kinda yellow, but after a day under the cotyledons are green, and they are standing up straight. From there the first set of real leaves grow in, and then they just seem to stop growing from that point. I have no idea what it is wrong. The first time I had some schultz gardenin…

was in my growroom this morning doing the usual checks,when i noticed a nearly mature bud,full of mould,this is two crops in a row where the bigger buds have gone mouldy,does anyone know any cures other than heaps of airflow.hydroshop says one dose of budlink will stop mould throughout the plants life,wouldn't you have to add it with each nutrient change?

Hi, I am having a slight problem with only one of my eight plants i have under 400w HPS and 80w Fluro. They are in a flood drain cabinet type setup. 6 of the 8 are Afghanis. 1 is Malawi Gold and the other is outdoor temperate. The afghanis are fine and going strong but the other two are slightly older and one of them is looking a little yucky.( its either malawi or outdoor silly me for not labelling properlly) Its showing like yellowing/lighter green on the edges of the leaves and the tips are also a little burn this is an over fert problem i know but its been remidied and now all i have is funny dark green leaves with yellow edgs. I dont think its a big deal or will kil…

I presume that most people will disagree with me here but stiff. I soaked my seeds overnight in distilled water and when they started to crack, I put them into 1" growool cubes as thousands of growers do. When they got to around 2" tall I transferred them to the grow room. I planted them in expanded clay and had the watering system on for 15 mins and off for 2 hours. Result, half dead seedlings. After posting some pics on here, I was told it looked like they could have root rot. I thought "rot", couldnt be. I was using Phytoff and Oxy Plus. Well, lets cut it short. They were right. Those stinking, useless, seed killing rockwell cubes were at fault. I was told th…
