Not enough water dude, and no more Big Bloom till flowering

needs more water and less nutes.

now there is some discoloration on the leaves the edges are dark green and the and a bit of light green, I am going to flush it, I think it got nutrient lock up but i'm waiting for the soil to dry up. so hopefully this will help my plant. Damn that sucks and my plant was going so nice too. oh well thanx for the reply

I'm thinking more of a lack of something. Not lock out. Might be boron,calcium. some of that looked like bugs, mybe of even a nute splash "burn"

they don't look to bad everyweek on the nuets does sound to much, if your sure all your ph's are correct have a gander at this http://www.icmag.com/ic/showthread.php?t=11688

nutes look fine. no hint of burn on the tips or edges and no signs of stress. the necrosis on the leaves looks like it could be a diffencency. more water though its wilting because it needs water

I had some burns that kinda looked like that. Not over nute, a spill/ slash on a leaf.

I flushed my plant yesterday and this morning it looks a lot better, it really picked up i'll try to post another pic later.
