Cannabis Troubleshooting

hi can anyone tell me how to effectively use fongarid in a recirculating system with rockwool instructions say 2gr per 2 litres of water added to soil. so i mixed 10gr in 10lts of water and drenched each slab (media) with 1.5lts and allowed the runoff to circulate back into the nute tank. does that sound ok? also can i add h202 when using fongarid? i know h202 is non-systemic wheras fongarid is systemic so i figure it would make a good 1-2 punch for pythium

hey, got 1 plant with slight yellow leaves more in the middle area of leaf. Using AN nutes at around 1.6 ec and ph about 5.8 botton feed perlite.....the other 1 looks ok same conditions and same base tray. ANy ideas, ta.

Hey guys, after a little advice if ya dont mind, had a look for myself but found some conflicting info, hoping one of you might pick it straight away. Growing in soil, ph is about 6ish last time i checked. I've been using Flower Power A&B nutes, only every few days though. The leaves at the top of the plant only are turning yellow between the veins, the tips are curling down, and there are a few little brown spots on the edges. From what I've read it may be Fe, Zn or Mg deficencies, does that sound right? Any help is mucho appreciated. Cheers.

I found this on the Amsterdam Seedbank and wondered if it is true... I have a few balls happening today on my WR, but they only have a day or two until chop so I'm not stressing. I know that they have done this due to the stress I've had them under lately but I am wondering how true this statement is in your opinions. Also how long does it take a pollinated female to start showing seed - a week or so? Jimbo

Hi all, I hoping someone can help me with some experience on this problem .... I cut my clones from flowering plants ... these 'mother' girls were all making seeds and have now been cropped .. the problem I have is that it seems all my clones have jumped right into making seeds again and I can't understand it .... they started making seeds almost immediately ... the question I have is ... do clones taken from plants that were seeded, automatically go into seeding when they are put into flower? I vegged all the clones for weeks before turning them to flower and it all looked fine until about 10 days ago when I noticed seed pods all over the place. Not only are there l…

This is by far the biggest and most healthy looking(to my amateur eye) seedling I have grown thus far. Does it look healthy to you guys? It would be 2-3 weeks old by now(counting the first day of soaking as day 1). The soil composition is a mixture of seed raising potting mix, peat and midrange(not premium) potting mix. I was experimenting with different mediums so I cannot tell you which is which It has been given one small dose of tomato fertiliser(way less that the recommended amount) and a touch of epsom salts. It has been grown under a large CFL (equivalent of 500W with 6.4k light output) with a few normal smaller CFLs in a mini-greenhouse indoors. Th…

Hey all, As per my diary thread here HERE, these youngins are doing the same thing as my last grow which I ended up ditching all but 1 'survivor' - the others just stunted and sat there. So I Fed these only water for about a week, then did a very weak mix of my nutes & microbial after flushing the res and they went well for another couple of days and then did this. I have reverted back to only ph adjusted water & microbial hand fed for the last 4 days with a good drying out period and they still seem to be yellowing and dying off but not as quickly and im not sure now if they are still burned or asking for some juice?

I'm in deep shit. I'm 4 days from harvest and I went to check on my plants. Half of them look almost dead due to no water for 3 days. There in Coco. I'm suprised they dried out so quick. Can I just harvest in 4 days anyway?. Or is all lost?.

here is a shot of what I think is heat burn. The seedlings are at day 14 under 38watts of growlux fluro in soil in my very first stealth grow box:) edit:just realised its in wrong forums, i would appreciate a MOD moving it...cheers!!
