This has been getting slowly worse for the last 3 weeks. Can't seem to figure it out, it started out as little spots and I thought calcium deficiency so added calcium nitrate, switched to calcium acetate in flower with no effect. Also added magnesium sulphate in case it was mag def. It slowly...

Plant problems, can anyone diagnose? Soil pH is around 6.5 Fed at EC1.0 about a week ago and they have done this. ive always grown DWC and never have any issues and i just dont really know how to diagnose soil issues could it be overwatering?

Hi all. spotty leaves, not sure what's going on. Please help! looks like calcium deficiency maybe? Strain: Gorilla glue #4 autoflowering. First time I've ever grown this strain. week 4 from germination nutrifield two part nutrients plus nutrifield bud burst. RDWC EC 1.0 - 1.2 PH 6.3-6.5. I let...

Hi, I am currently in the process of changing my entire grow over from flood and drain using clay pebbles substrate to DWC. One thing I failed to consider is that my grow is big. Really big. I use 1000 liter IBCs cut in half, and grow a SOG consisting of 30 plants and I run 8 of those units so I...

Hey guys. I'm having some issues with my flood and drain garden at the moment. The strange thing is it's happened the last two cycles in a row, but never happened in the many cycles before that, and isn't happening to another flood and drain table which is fed from the same nutrient tank. The...

Soil ph around 6.5ish Strain is critical kush auto Under 600w led Ignore the white marks, that's just residuals from a cal/mag foliar spray. There are just a few plants with leaves like this, setup is a 4*4 SOG with about 80 plants from seed, one particular phenotype seems to be doing this. I've...

Howdy. I germinated a run of Auto CK two weeks ago, I used my usual hydrogen peroxide method which typically results in 95% germination in a day or two, but as the seeds were a year old and I had some gibberellic acid I figured I'd use it, as a quick forum search indicated people use it...

Hi all. I'm planning to refit three COB led fixtures I have with CXB3590s. I originally built them quite a long time ago with cheap chinese COB chips. this was back in the days when the growing world had just graduated from "blurple" to 3000-4000K COB chips having come to the realization that...

Howdy. I have what appears to be two different problems. The first one is light green patches appearing on leaves which has just happened in the last 48 hours. Not sure if its early stage N deficiency or possibly potassium or magnesium? I've been looking at the deficiency charts but it's hard...

Howdy. I've just finished my first run in clay pebbles. I switched to flood and drain after seven years of using coco and I'm pretty impressed with it, the grow went really well. So now I've pulled all the plants out and as much of the root mass as possible and I'm ready to get another lot...

Hi. I've got a couple plants with what we're pretty sure is calcium def, but also a bit of nitrogen toxicity and they are in week 2 of flower (autos). I ran into this about year ago and foliar sprayed a calcium nitrate solution which fixed the cal def but made the nitrogen abundance worse, which...

The clawing I'm pretty sure is just nitrogen abundance, but I'm a little lost on the others. Nute burn and something else perhaps? I've flushed the beds with water and loaded up a lighter mix in the tank today. Thanks in advance TGS

Hi all. I have switched from using coco to flood and drain, and this is my first run. I'm running 18 x 14 gallon tubs with clay pebbles, they are fed from an 80 gal reservoir. When fully pumped out the nutrient level comes up to about an inch below the surface of the pebbles. It pumps up in 8...

Hi all, I have previously had seeds shipped by stealth shipping from Alibongo seeds in the UK, but it seems I can't use them anymore, I don't know why but payments to them keep failing. does anyone know a seed bank that will sell and ship to Australia? One with a very good stealth shipping...

It looks like cannabis will be decriminalized in my country next year (still technically illegal to possess and highly illegal to grow without a licence, but no prosecutions for possession) . It's already been decriminalized for the terminally ill and CBD has been legalized. There is a public...

Hey there folks, couple pics attached of my QB22a build. It's 15 strips all in parallel. Running my own home brew drivers I've built 4 of these, and just wondering how the driver efficiency compares to that of meanwell drivers which everyone seems to be using. So I'm running my strips at 11.05A...

Hi all, I think I've found some thrip damage. Can someone confirm that's what they are? Do they need to be dealt with and how urgently? There are hardly any of them, plants are Autos in week 3. Photos taken under microscope.

howdy. I have noticed what appears to be a calcium def on a 2000sqft site I'm running. growing autos and they are in week 9 from germination. this strain runs about 13 weeks to finish and they are just beginning to fatten up so time is of the essence. checked soil ph and it is around PH5. can...

As the title suggests, wild deer are starting to make an appearance and I need the best deer repellent money can buy or that man can make. I'm currently relying on bullets, which although the best deer repellent in existence is quite labor intensive as it involves sitting there all night. I have...
