Burned circles on all leaves eventually killing them off...pls advise!

I have been growing for couple of years now, organic soil with some perlite, vermiculite, bat quano, bone meal, dried blood, garden lime, all organic...HPS 600, it has always worked great. I just recently haven't used as much vermiculite, because it freaked me out that breathing it in causes cancer. But what doesn't these days right? Anyway, I always use organic staff so it might not have been it. I check the pH of my water every now and then and it's usually around 6.5 - 7. I am getting no results with these plants. I have also gotten some new strands (AK47, kandy kush and super skunk), the AK seems to have really thin stalk and kind of purple color, but all of it's clones do to, so I thought it might be the strand. I am at lost. It isn't getting better, just worse. They are drying up, not growing from the stress. Any suggestions would be greatly appreciated!!!! Really any suggestions please! Thank you in advance.

Also my pots used to be full of roots upon harvesting, but now there are hardly any...nutrition burn? Should I flash them? Any suggestions or experience with this?

Im not 100% but it could have been a rust fungus. That shit got me looks pretty simalar but it took out any leaf it was on. Hopefully its not that but it looks simalar. Ill post a pic of the rust fungus to compare it too. But could be too much phosphorus as well. Doesnt look heat related.

I would flush them though just water heavily with plain water but without over doing it no need for gallons just something clean.

pH fluctuations & over-fert issues (quantity, frequency) have probably caused some micro-nutrient deficiencies or toxicities (depending on which side of your pH scale you have swung).

This was my issue back whenever. But i was told it was rust fungus.

I was gonna say, jondamon had a picture up in one of his journals showing the onset of calcium deficiency, which looked somewhat similar. He said magnesium deficiency would look similar.

Find the out what your pH is, if its more acidic (lower number) then you are probably toxic (too many nutes). If you have a higher pH, it could be a deficiency.

Somebody chime in if I'm wrong here

its a magnesium def. The drainage is too fast and they probably dont have any cal mag. I got it from this. Its could alsobe heat issue

This IMO is calcium deficiency.

Starts out will small rust like spots.

Here is the pic I posted in my thread about Ca def.



To the original poster.

I would say there is a multitude of possible problems.

Initially I would say under fertilisation.

Root bound as your pots seem quite small from the pictures.

The white little dots on your leaves actually looks like spider mite damage.


So I ask.

What size are your pots?

Are you feeding anything other than what's mixed into your medium?

Have you checked for pests?

Here is a pic and description of Mg deficiency.

wow they look like a weed grew up in place of your mj plant, lol looks very unhealthy, sounds like it just needs to finish dieing off and start again, bigger pots better control of nutes and better care in your environment.. looks like you also have buds getting ready for harvest too so good luck.

Looks like theres to much nitrogen. Thats what kills the leaves like that at the tips and edges. Bad drainage or drainage into a saucer that just gets reabsorbed into the dirt causing lock out, the spots. Annnnnd high temps causing stretching. I hope its all that stuff because AK should never look like that bud. Good luck

Thanks, I just mixed up a new batch of soil, I didn't use as much fertilizers and I also thought, because I use tap water now, that all that chlorine is not good. I used to use rain water or I put fish tank staff to remove the metals. So I will start doing that again. It's not bags, I had spider mites a while back and thankfully they are gone now. I am also starting some new seeds and hope to get a stronger strand. Usually I do really well...not sure what happened this time. But I definitely let it go too far.

Looks like calcium to me and not enough nitrogen.
They are really stringy, even the picture in your avatar pic is really stringy.
I would suggest going with an entirely different soil/soil mix.
If your avatar is one of your grows, a long with the pictures from this thread, something is not right.
