Cannabis Troubleshooting

Hi guys Can anyone tell me what this faint dark marking is on these leaves? (the closest 2 leaves) Could it be a possible magnesium deficiency? Peace Ganja

Hi everyone, I have a batch of youngsters which are showing signs of problems. They've been going quite well but in the last 4-5 days I've noticed that new growth has gone an almost fluro bright green .. Pictures hopefully show the story better than I can describe ..they started in small rockwool cubes and I moved them successfully to 3" cubes which are now pretty full of roots.. Some of the cubes have developed a dark green colour on the top of the cube.. They have been under compact fluro and I've been feeding them .. I thought .. gently with cloning nutes.. It's possible I've used too much as it's a new brand I've never used before.. It's also possible I've kept t…

Not sure whats happening buts my girls are 5 weeks into flowere and the leaves are looking terrible.

Hey guys, first time poster, first time grower and long time smoker here. Trying out a single plant cfl closet rig, hopefully I'll get a proper led rig at some point in the future, but for now the bunnings rig is where it's at. The problem I'm having is that the plant has been outside since germination, just because I had no way of getting it to my place until now. So it's grown in a Far North Queensland climate and photo period for about 4 weeks now. Not great I know. It's been getting a ton of rain, maybe too much? I'm not too sure but the first leaves that came up have gone fairly brown, you can sort of see them underneath the main leaves in the photo, and also on…

The strain is thc bomb auto by bomb seeds. It is 17 days old, spent 10 days in jiffy pot, 10 days with 100watt t5 HO. Now planted in 7l pot with 30% perlite 70% organic soil. Under a 250w MH. I am only doing one because I only smoke once/twice aweek and it will be Enough for my needs and I think it will make it easier for me too focus on one plant. Can you tell me how u think it is looking? Is it too small? Thanks

Ok so some of you who have seen my grow diary will have seen some pics of my 3 plants, the 1 that went hermie ( which is a thread on here already ), and the other 2 who are females...At least i think they are.. They are all the same age, aprox 65 days into flower... anyway ive put some photos below with flash on and off i dunno if it can help you guys see what happening, maybe im just trippin balls? So heres the story - P1 : Has alot of nice bud sites and is slowly yellowing off as i stopped nutes and will be harvesting probably on day 70 of flower, However i have recently found about 5 seeds on this plant, it was by accident when i was taking pics i was moving some o…

We've been having a little war with the little bastards of late. Neem oil cuts the population down, but they breed back up in no time. I've been looking in to natural options. There's your Bacillus thuringiensis israelensis. The beneficial bacteria found in products like Gnat Off and Gnatrol. It seems that Bti is no longer available to the general public in Australia. I have found several mentions by different councils that use it for mosquito control, and I was informed that it stopped being stocked on Australian shelves about 2 years ago. I do not know what import/quarantine laws are involved if one was to buy it for overseas. Then we have Steinernema feltiae, a ben…

After harvest I spotted these buggers all over the stems, I already suspected I had them as I'd spotted the ants that farm them earlier in the grow. Every grow I've ever done outdoors has suffered from Scale Aphids and now they're a hassle for my indoor grow. As far as I'm aware these are very difficult to remove, Ive been through the previous threads and found a few answers and was wondering if anyone had a definitive way of removing these buggers. Thanks in advance.

I feel rather silly and I don't think I'm doing very well haha. I'm a first time grower, my little plant is about 10cm tall with very tiny leaves. It's at least 3 months old, it's not dying but it also isn't growing. It was initially grown on my windowsill in compost (yes, I know *facepalm*) It's now outside in a sunny position, it receives water and I have fertilised it (not too much) I just don't understand why it seems to be in suspended animation. Does anyone have any idea what may be going on?
