Help 1st grow plants are die'n!

Ok iv seen several posts similar to this but none of the pic's quite matched up to mine ill post them here in a sec. but basically the leaves are yellowing. they were introduced to their new room 2 days ago today being the 3rd. I have no idea what to do. im using a 400w hps that's about 30 inches above my clones. humidity and heat have been rather high sitting on about 85 and like 40% humidity. got the humidity up today to about 55% and temp @ 80. heat stress?

forgot to say brown spots appearing in the middle of the leaves. waiting for the camera to get here to post pics.

Sorry it took so long for pics. anyone?

and they were fine 4 days ago? How old are they? You feeding them? My very first thought was nitrogen deficiency...

yea when i got them from my friend they looked healthy as can be nice and green. im using flora blend i think its called watered with epsom salth the other day lowered the ph to about 6.0 i also have floralicious grow but i have yet to use that.

no progress lookin worse every day would love it if some one could help!

i would be looking into a possible cal/mag deficiency. nitrogen tends to just be a yellowing i believe

im with diowk , looks like nutro deff but im not sure , how long ago where the clones taken from the plant?whats your light cycle? i would piss of the epsom salts even if it is mag deff your clones are just better off getting a decent feed , i would make up a very light batch of nutes and mist your plant once 5 days see what happens.

will do thank you ill keep ya updated

ok so iv got flora blend im using at the moment mixed about 1 table spoon in 2 gallons (recomends 1-2 per gal) so thats what im misting with. i got a tds meter. i have no idea what it dose but my ppm in my dwc set up is 345 and in the misting water its about 150 something. ph is at 5.5-6.0 in the dwc and the misting water. i cut the big yellow leaf in the 6th pic to the right (sweet island skunk) i looked today and her root is just now poking out of the bottom of the pot and feeling the bubbles. looks like its doing better. i also installed an inline fan so temp is maxed @ 85 and humidity is at like 50%. is the flora blend enough? what ppm should i be at?

spraying once a day using a little bit of floricious grow. 2 are looking very healthy but there all still yellowing. the root's are rapidly starting to poke out of the bottom of two but not the other two. the other two have no roots showing through the pot yet.

give plenty of water and spray with water everyday lose the dead leafs should be fine in no time

some leaves are dieing still or appear to be. just gave the lady's some home made c02 (sugar and yeast) yesterday and from the looks of it there diggin it. i was thinking about topping all four of the ladies off and hopefully growing two - four cola's. i read top off 4th node up and iv heard 2nd but these are where my weaker leaves are and i don't want to make a mistake. so should i wait until they look healthier? since i cut one node off dose that one still count? should i spray with water and floiar feed? and should this only be at night ? or foliar feed at night spray during day? ill get more pic's up today might get a snow white clone too.
