the curling....

im pretty sure it's not calcium or magnesium

Looks like potassium deficiency... and its not supposed to be happening.

 

[motoracer110]

the buds look good but to me the leaves look like nute burn.

 

[motoracer110]

are you using full strength nutrients?

help? ideas people?

 

[gotot]

could it be bacteria? b/c bacteria just killed one of my plants

 

[InsaneMJ]

maby a lack of water, and like the other guy said a lack of potassium because that happened to a few of my plants, if anything try to give it a bit more nutes, and cut off the burned partes

thats an easy one.
TIP BURN.
causes.
(1) tin foil/reflective heat tip burning.
(2) too hot/lights too close.
(3) windburn(fanning).

[KodieD]

[LUDACRIS]

windburn? dont see it

hot wind waves are quite hard to see.
tin foil is your prob mate had it before.

I don't think it is nutes as much as heat. It looks like you may have light to close to plants.

I think its nutrient burn. You may not be adding too much, but if you are growing in soil it may already be at its full holding capacity for nutrients. If your plant isn't using all of the nutrients you're feeding it, they will remain in the soil. If you keep on the same feeding schedule this excess will build up and eventually burn your plants. I don't think it's heat stress, if it were, it would be really bad at the top of the plant and less damage at the bottom. Looks like its pretty much all over. I would just feed with plain water for a couple weeks, can't really hurt. If you've been feeding regularly I doubt its a deficiency. I would say there is a 40% chance its the heat and a 60% chance its the nutes. There's my two cents anyway.

I'd guess over-fed and too high temps. So you give it food to produce when the plants telling itself to start using the built up nutes from the grow . . . and then, in nature anyway, the temps would start lowering at natural harvest time, perhaps?
I've read several times that a 15*F drop while the lights are out is acceptable.
Those canoe-ing leaves may be too close to your source.
