crunchy spotted leaves help lots of pics!!!!!

i am just going to let you know this:

400 watt HPS
humidity 23-33%/temps around 81 degrees
fourth week flower entering week five
6.8 ph
all organic foxfarm soil and nutrients all organic


fan leaves all really crunchy and spotted seems to be rapid with the way its taken over my plant please help!!!








as you can see the one on the right is most affected and the one to the far left is starting to get affected!





















here are my nutrients (advanced nutrients iguana juice bloom and overdrive)

Have you flushed? Looks like nute burn to me! If you havent flushed use 3 times as much water as the size of your pots. Five gallon pots get flushed with flfteen galons of water. Or use Clerex or Florakleen and it takes a lot less water to flush! Check your runoff and see what the EC is or what color it is.Yellow water means flush time. Good Luck! Looks like a nice strain. What is it?

You have foil on the walls too. Foil is bad. Creates hot spots and could be a big problem too! Off white flat white paint is much better for reflection.

aww i see so i would have to run about six gallons of water through their soil cause ithey are 2 gal grow pots i see.

now i am going to be honest of course and i have not flushed quite yet i have had a little stoner procrastination and also am gald to be talking about this right now, as you see i don't have an ec meter (stupids i know tell me about it) but that is a tool i am lacking and always wondered up untill this point exactly how i am going to flush and not fuck things up bad not knowing the ppm and what not..

i honestly dont know if i should go flush them in my bath tub with ph'd water and see what happens or maybe thats not such a good idea?

i was thinking they needed a good flush..

any ideas how i should go about this?

p.s. its really healthy bag seed but i have taken pride on what awesome genetics of these plants that i have stumbled upon...

i also have seven rooted clones from these.
and the plants your looking at have been started from seed vegd for 31 days

actually its a insulated mylar kinda like a bubble wrap with mylar on it, on both sides its 10$ for about 15' at a home depot its good stuff.

yer ph is a bit hi I think flush and lower to 6 that looks like locked out nutes to me.

6 ph really?

thats not a bit low for soil?
then again this is only my second grow.

i must say i agree with human thats what it l thought when i seen them or you could have root rot if you use grow bags you could cut the bag to see if there's brown roots if so put 2 inches of perlite in bottom of new bag, no shock. you should always use 2 inches of perlite in my opinion.
