4+eeks in and leves are yellowing and dying..help don't no what to do

in 4 weeks in and leves are yelowing(top and bottom ) I'm using house garden nutes and fox far ocean soil onder 600w lightsabout 10in above the plants...this is my first grow everything has been grate till this point..my ph is arownd 6.1-6.3...

do you have pictures?

your lights may be too close to the plants 8 weeks of veg if from seed their probably small and new tissue is burnt quickly, use the hand test, put your hand under the light if you can feel the heat its probably a lil too close 600w should be 16-18 inches from plants especially new plants... you also could have over nuted and burned them that way..or you need to flush and havea salt build up which is locking nutes out yellowing in a sign of lack of nitrogen but it depends on how it looks as its losing the color which will determine what the cause is you'll have to post a picture to get a direct answer

I tryed to put a pic I don't no how to do it from a phone

they where clones and veg for 3weeks

anybody have any ideas

they started out with spots on the top leves and the bottom leves turned yellow and died
