How you doing , i'm a new grower and I'm running into some issues in my vegetative stage . The problem is my bottom leaves are now turning yellow and this vain/ stem in between the leaves are remaining green I'm going to post some pictures so you can see what I'm talking about .Can anybody tell me if this is a magnesium deficiency problem or a nitrogen deficiency problem ???? Oh and for some reason my pH is running about 6.6 in pure Coco I've been adding distilled water at 5.8 to bring it down any other advice as far as bringing my pH down ? Just give you a quick rundown of my set up I'm using a 2 x 4 tent going in at 3 gallon pot of pure cocoa from General hydroponics Coco tech and using a 600 W LED light image.jpg image.jpg image.jpg image.jpg pure Coco I've been adding distilled water at 5.8 to bring it down any other advice as far as bringing my pH down ?

looks like nitrogen deff to me.
6.6 ph is just about right, add veg nutes at quater strength or half on your next watering or you can foliar spray up to you

I would check my tap water and see what the ppms are, if it's below 300, probably ok to use. I would also check with my city to see if they use chlorine or chloromine

best thing you could do though is get a r/o unit, $95,everything you need http://www.purewaterclub.com/catalog/product_info.php?cPath=67&products_id=264

I don't grow with L.E.D, But I think they like more cal/mag under them, but you might want to check that info
I think I might just do that thanks , is it a lot to set up , i've never used it its foreign to me the r/o system that is

it comes with a hook up for supply water, a hook up for waste water, then you need something to collect the good water. Just be careful of the waste water, it can eat pipes after long term use. I would also get the 1 to 1 ratio filter upgrade for that unit.
