Nothing I Have Seen Before

[dutch.lover]

I have some dark spots on quite a few of my plants leaves, I have never seen this before. Can anyone enlighten me? I am guessing it would be some sort of nute problem, except I don't think any of my plants are suffering from anything other than this (check out my grow log thru my sig, i just posted new pics of my vegging plants). So anyways, here are some pics.

Dude you sure better look on the underside of that leaf in the pic!!!!! That looks just like the mite damage that my gurls suffered! Got a magnifying glass?Check for the crawling critters!The damaged parts on my leaf was white to brown to black! They even started to yellow some as well!I know for a fact my problem was not nute burn! It was FREAKIN' MITES! I hope it is just a nute burn!

Ga Grown!

i really really hope you ARENT right. lol. We had a thrip problem (still sorta do actually), and therefore we have been spraying with insecticide like at least every week for the last couple weeks. so i would hope that it would be unlikely that it's a pest problem...but maybe i will go spray all the plants down again. fuck that. lol.

come on guys... not one of the 25 who have looked at this knows whats going on? i have checked the charts with pics showing defs and burns, nothing seems to match up... i shouldn't have a pest problem, as mentioned above... anyone know? I have no clue what it is, and i would really like to fix it before it gets worse.

I did'nt say it was a pest problem! I said you should check!Try flushing and foliar feeding with plain ole' ph'd water.I'm just trying to let you know that the signs were the same.Does it look like a fungus,to you? Sulfur would work in that case.

I do believe that I read such symptoms occur from root rot. Also the downturned leaf edges, as well as the discoloration could be result of some type of deficiency. There are plenty of guides that can walk you through that, but I'm sure you know that.

Didn't read all the posts first, sorry. Well anyways. It could be multiple deficiencies instead of just one. Look for terms such a necrosis.

Is that a peat-based soil?

[dutch.lover]

i wouldn't say it is peat based, but it has peat moss in it (along with top soil, sand, perlite, and worm castings). We pH'd the soil too btw, so pH really shouldn't be an issue. hmmm maybe I will flush them just to be safe. any other ideas? what were you thinking stinky?

[stinkyattic]

I'm thinking that your pH-ing didn't 'take' and that you have a serious pH problem. I've seen that before. What is the sand? Does it have limestone in it? Did it have a reddish tint indicating high iron? Minerals in your soil are BAD because they make it really tough to feed properly or keep the pH stable. You need to use totally chemically inert agents like perlite to make the soil more friable wihtout adding minerals by mistake. I'd take that sucker right out of its current pot and shake off the rootball just a bit, and repot it into KNOWN good soil, and then give it a nice drench with water at pH 6.8.
