What the Funk?!?!

Ok I'm pretty confused as to what's going on with my plants, well plant actually because it's only one plant having this happen. I'm hoping someone can give me a little insight as to what what's going on. I was getting a little discolouration from using half strength 25-10-10 (No, I don't use it every time I water.) so I cut back to quarter strength and all the other plants seemed happy but this one is goin wacky. I'll let the pictures do the talking.
Also, preflowers yay,







P.S. Droopy from being watered shortly before the picture.

That picture with the arrow to the leaf is a zinc deficiency. I've pasted a link in this thread for plant problems.
My advice would be to flush and use nutes made for mj and not something off the shelf at home depot or some other commercial store. Here is a good place to get stuff.
I also use Cal-Mag Plus and compost teas and micros mixed in with my nutes which normally has all the stuff you need for healthy green

Heres the link: Plant Problems

I hope this helps
