need help asap before its too late

Ok so here's the deal. I have 3 plants growing one super sil. Haze and 2 B52s. A couple days ago I asked why my leaves were curling up. No one could really give me a answer. However I went to the grow faq. I went to the ph/nutrient section under plant problems. It said the mg was low. Well I am using magical by technaflora. I do have epsom salt but I'm not sure its a mg deficency bcuzz I also found a section in the faq under the same ph/nutrient section that said ozone pollution or something of the sort. Now 2 days later 2 of my plants have the brown lines in the leaves as shown under the ozone section in the grow faq looks identical. But problem is I live in the country I have good air circulation and no source to polute. Can anyone tell me what's going on cause I don't want to overdue the mg if its not it. Please help me!!!

Flush them with plain old water wait a few days a see if the perk up.

I think we'd all need to see some pic's before we could be more helpful. "Leaf curl" comes from a lot of things -- curling down like a claw is usually overwatering and/or overnutrition of multiple elements. Curling along the long axis into a "tube" or a straw is often underwatering, especially when accompanied by even the slightest droop at the leaf stem joints. I've seen some Mg deficiency and "pH problem" pictures that look like this too but, frankly, I often wonder how people get these "example of deficiency" pictures in the first place. Did they do actual soil testing of all these elements to see which one fell short? That's costly to do properly, you have to outsource it, and just 'cause a plant shows problems and you add something doesn't mean the repair was caused by what you added. I suspect there's a lot of "deficiency photos" on the net where people were really just guessing.

Unless someone explicitly states how they made the determination that "my pH was low, so the plant exhibited this-or-that symptom", I'd take these things with a little grain of salt.

The thing I would recommend is to ask Dr VonDankenstein.. check the "General Growing" thread. The Doc knows his shit. His latest "Ask" thread should be in the first few pages.. might want to get in quick before that thread closes; it's been going awhile. The Doc will need pics, too, to be able to help you clearly.
