small leaves that grow out of the bud turning brown??

has anyone else had this and is it a problem... all the other leaves and fan leave are fine just getting some browning on the tiny leaves that are growing out of the bud??
thanks peeps

You should post pics, it could be any number of problems.

heres a pic..

anyone come across this???

Alright mate, looks for the picture you takin its turning a bit purple, could be your strain, light problems, nutes, etc..etc.. If you include your setup information and your plants age I can get back to you.

thanks for looking mate, its def brown and a bit crispy.. its week 6 of an 8 week strain of indica/sativa hybrid.. running 2 600 watt lights in a iws flood and drain, temp are between 70-75. at first i thought maybe heat stress but theres other plants that are the same strain which are closer that are fine? and with nutes ive kept the dose really low because i have no ec meter. i ran pk 13/14 a couple of weeks ago for 5 days other than that just ionic bloom and boost? all the leaves are fine just the ones around the bud on 3 of the plants (out of 10)? im baffled? wondering whether to use gh ripen and finish them just over week 7?
