also, this looks like a nute deficiency...its important to note what soil you are using and if you feed them, i would take this post to the plant problems section, you will get very good help there...for future reference, you should add perlite to your soil mix
 
the leaves twisting could be an indication of a ph problem. It looks like an N or mag deficiency or lockout. I would say flush for two days with Phed water (6.5-7 for soil) and then try a round of nutes at 1/2 strength. This is the third time this has happened?? Have you changed the soil mix your using? could be throwing your ph off.
 
i live in europe and the soil u probably wouldn recognize its a german brand the name is seedlings has a ph of 6.5 i used it before i grew 7 diferent strains in it and had no problems,this is the first time i see this condition,to me it looked like a n deficiency but it started after 3 or 4 days thats a little to soon for a deficiency and it started as drying and twisting of the leaves leater they got yellow,about the nutes i did add a little fert. in the water about 3 days ago 1/4 stenght 10-5-6 ,and it didnt help,i didnt want to do stronger becouse i got organic fer in this soil and i did put perlite u just dont see it on the pics becouse i covered the surfice whit some soil becouse the organic fert smells bad .i have a ph meter dont know how to use it couse in the instructions it says i have to submerge it in a solution and ajust the ph whit a little screwdriver in the back of the device if somebody has expirience whit this can i use some other solution couse in my i cant find to buy this solution i ordered the ph meter over the internet but now i dont have 2 weeks time to wait for the delivery
 
do you have a pet store?? go get the ph strips or litmus (I think thats how you spell it) test. They have high and low range usually and sometimes come with some PH up/down scauce. they work ok till you can get a hydro specific up/down and some calibration fluid.

The meter will need calibration fluid that is 4.8 (I believe.. check your manual) And then one that is about 7ph. You adjust the appropriate adjustment screw as per your manual for the low and high Ph. Do the low one first and then the higher one. so yes.. you will have to order the two calibration solutions, but go get the aquarium ph tester to check for problems.

way too soon to be adding ferts, if that saoil contains some already, then your good for the first 3-4 weeks, i think you got straight up nute burn , flush! then wait a couple more weeks to start adding nutes, remember 1/4 strength
 
i flushed yesterday,il check tomorow at the pet store to see if they have these strips, morrisgreenberg i dont think its nute burn couse this started way before i gave em the fert.
 
holy shit. You should work on your writing skills. I find it hard to understand you with 7 because's in one sentence.
 
some guy, id have 2 agree with u bro, looks like a ph problem if the ph is fine then its the deadly chlorosis noooooo na its not tht bad , but it does look like it, well some of the leaves not the dry 1's ,either way its a magnesium or iron defficency treat it with epson salts google it an compare it 2 your's but first do a bit of research, it could be just me but alot of the more leafy plants tend to get chlorosis easier it may be due to the larger leaf area needing more mg or iron but ive seen it quite a bit in leafy varieties
 
what is chlorosis,now my 5th plant which was younger then the rest started to show the same signs it was all good for 10 days and then it stoped to grow and the leaves started to dry on the edges and twist,im growing in the same soil dutch passions euforia and white label's purple haze and everything ok there
 
chlorosis is when your plants start to turn yellow like yours are, from partilal failure to develop chlorophyll. Caused by a nutrient deficiency, or pathogen.(any disease-producing agent) I say you get a neutral medium with perlite, and risk a transplant.

you asked what chlorosis is some one else already beat me to it, but just to add to what was already mentioned, its usually either a lack of one of the 3 if not all, magnesium/iron/calcium i find it mostly happens in leafy varieties like the one u have there, in my opinion indica domminent plants tend to go through there micro nutrients quicker than more sativa'ish strains what i mean by this is there secondary nutrients like iron & baron etc. more quickly than there primary nutes like nitrogen/pottasium ect one way to deal with it is to add epson salt or buy a bottle of calmag from your nearest grow store :hump::hump::hump:
