Howdy all, This is my first grow so lots to learn but so far I haven't been able to pin down what's wrong with one of the plants I'm growing. Basically the leaves are a mottled colour with patches of yellow in them. The leaves also don't look smooth. I'm growing 2 other strains that are not showing any problems. I have been feeding this seeding for 2 weeks using Canna Classic A & B using the amounts as specified on their website, I'm feeding them once a week only. The only issue I had was leaf burn when it was a very young seedling due to low humidity, this is no longer occurring however the humidity in the Grow Tent is still below 30% I've attached 2 photo…

Hi guys, run into a bit if trouble hoping someone can spare some wisdom. Apologies for the poor photos the last shows the problem best! Growing in osmocote premium potting mix (contains controlled release fert). I understand this is a poor choice in soil however I have read of success with hempy's using osmocote controlled release as the primary fert (note this isn't a hempy setup however), and I can't always be there to ensure they are fed properly so figured I would give it a go. I have been very gentle with the only feeding thus far and will continue to be careful as the plant is obviously getting a small but regular dose of nutes. I am using Dutch Master Original n…

This is mostly an experiment so I'm not going to be heartbroken if it fails. There were two major problems. First, leaves started curling and drying out. They were growing quite close to the lights which I measured at around 60C - so I assume they…

I'm growing indoors, in perlite, hand watered once a day, ph is around 6, day temp 24 -27 night 20-24 degrees, using a cooltube with a 400watt MH, they are 5-6 weeks old & are in the veging stage. For about 3 weeks now they have had brown spots on them as well as the leaves have been all wrinkled some curl upwards & some curl downward's. The bottom leaves seem discoloured. I'm also using canna Aqua & Cannazyme & rhizotonic.This is my first real grow of a named strain & not just some bagseed.So any help would really help.

Hi guys, got a bit of a weird situation that I've done some searching about but can't find an answer. So I have one plant outdoors in coco which I started flushing yesterday as the number of brown pistils was increasing pretty quick, and growth had stopped for a solid week. I can't tell the trichome colour with my 30x loupe, maybe because I'm colourblind. So yesterday I noticed most of the leaves had started curling upwards and the tips were dead. I read up and found this can be caused by overwatering but in my case I don't think so? I've been using Canna A+B the whole grow and have had no problems whatsoever till now. I also noticed bright green spots all over the bu…

I have two seeds from known source that I germinated in paper towels. I then placed them in rock wool, just gently below the surface. Root pointing down - water used was ph adjusted - in plastic starter tray with lid. Tray is on a warmer - ph 5.7 - temp 26degrees - light is brand new compact fluro. 14 days have passed with no sprouting..? I placed a small piece of vermiculite over the seed 'hole' after the first week just in case the light was the issue. I have no idea what could be wrong - any tips would be appreciated.

Hi crew just a question for anyone who may know, I have a female white widow that has been flowering for 67 days in cupboard, scog perlite/coco medium. Having chopped main colas at day 63 when trich's were creamy just as I prefer, I placed the plant back in flower cupboard after being in darkness for a cpl of days to see what would happen. It appears to have started to self seed. I can't see any bananas, though I have had this plant throw bananas this late on other grows. I will try to get some happy snaps up. My question is will the seeds be hermi or wishfull thinking viable seeds, or should I just pull her out to stop the risk of crossing with a sativa that's about two…

Hello people, anyways I got 2 plants off my uncle about 3 days ago didn't look like there was an issue with them but since yesterday the leaves on 1 plant have gone crispy brown the other 1 seems to be slowly getting a couple of brown spots here and there but nothing to concerning just yet. As for the soil I believe its half decent stuff, for the nutes he was using thrive. outdoor plants btw. Here's some pics. I live in Perth and where currently experiencing a heat wave so possible under watering maybe?
