Cannabis Troubleshooting

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…

Hi people. I have this green ( i think its algae ) stuff growing on my clay balls. I was given this little system and have no experience using it. If its green algae what can i do and is this a problem? I appreciate any advice given thanks

Throw me a line guys, just did a watering, one of my babies is getting chlorotic? leaves. Yellowing leaves with green veins. I know its a deficiency of some kind, but the memory can't recall exactly what. Been poring over the High Times and Max yield issues, but as always, the issue you need is nowhere to be found. H2O for tonight's menu, but would like to resolve by tomorrow evening. A coupla pics.............

Some of the leaves on the lower half of this plant have gone pale with white spots. I took a photo of the most severe area and noticed little red things on there, are these spider mites? and would they be the cause of the pale/spotty leaves or would it be coupled with some kind of nutrient deficiency? Thanks

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.
