stumped, a lil help please

i have googled and looked all over but this problem is affecting my plants within 1-2 days it comes on fast and the leaves end up drying to a crisp.i only mist them once a day with a light veg foliar spray.i have also flushed each bucket thinking i was over fertilizing.

i am using sunshine potting mix and fox farm nutes as directed,my soil ph is a healthy 6.5-7 in each bucket.i do not water but 1 time a week or so as the containers are pretty large it takes quite a bit to dry out.
3 150 watt hps bulbs and 4 300 watt cfl's all far enuff away as to not light burn the plants.
this is my 3rd grow and no issues until now.i have had to sacrifice 3 plants so i can have some nugget saved.oh ya also this starts from close to the top and works its way down.

no thoughts anyone?

Foliar feeding while budding is a bad idea to start with. But you already answered you own ?. Looks to me like they are overfed/watered.

Yeah, I agree, it looks like overfert. And I also agree that you are asking for problems foliar feeding in bloom, especially every day. Looks like you've had some nutrient lockout going on, showing some deficiencies. Is that why you've been foliar feeding? How long? I haven't done much foliar myself, but from what I've read, you should spray with straight water in between feedings, so that the leaves get rinsed and can breathe.

You bet. Salts can build up on the leaves just as it can in the medium. You can even use soda water for the cleaning. Gives them some CO2 to boot!

actualy by misting i meant straight plain water , i never have felt the need to add nutes also because my plants are always a healthy dark green with speedy growth.
but ya once the prob started i flushed the soil and it takes quite a while to dry out to water again like 1 week minimum.
taxes coming back i am going to try a hydroponic n see if i do better.
i have a habit of double guessing myself i hate to jumop the gun n realy mess em up.at this point i just going to let em ride do or die.
i have 20 clones ready to take their spot.hehe

thanx all for the feedback.

Even misting with plain water during budding is a bad idea. You are just asking for mold/fungus/bug issues.
