My white widow has yellow leaves!

Hey everyone I'm a new to growing and I'm in my second week of grow after seedling and my plant has started to go yellow and has some red veins in the leaves. I'm not sure if it's sulfur or nitrogen deficiency if any!

I would say ph problem in conjunction with too hot. how close are your lights? The red veins are actually ok and normal so since it is on under side of leaves where it is shaded, heat and ph are my best answer. try and get your temp between 70 and 75 get some ph down and adjust to around 6.5, and back your light off, it doesnt need to be very close to such a small plant. hope it works out for ya. Also if ph is bad then nutes wont work properly. I use general hydroponics nutes at 1/4 strength for that size plant which would be 1/2 ml of micro 1/4 ml of both grow and bloom add to water then ph it to around 6.5.

Looks like to me it needs some weak fertilzer there. Does your soil have any in it? Are those hairs growing already I never grew autos before and how many hours of light does she get

Thanks for replying guys..I haven't used any nutes yet but I have AN ph perfect micro grow bloom that I was planning to use but didn't know when and the plant is not having any heat issues from the light.
Today when I checked the lower leaves were the ones who turned yellowish so I'm thinking of nitrogen deficiency but I'll start using my AN nutes but how should I prepare it for the soil?
Btw the light are on 16/8

More than likely needs fedding...

I never used them but I read up on your AN nutes and liked how they can adjust ph in water anywhere from 4.5-8.5 . My tap water sits around 8.3 to 8.5. They suggested 11 to start. It looks like like the ratios are on what suits you. Again I have no clue but you should start light at first

Whats the tube running threw the bucket? But yea your having a nitrogen def. You may have under fed it during the vegging stage.
