1st timer help?

Hey, New to this whole thing. This is my first shot at this. Im running a 400w hps. 2 plants from bag seed.Im wondering what the yellowing is on the leaves. The leave eventually shrivel up and fall off. Ive been on 12/12 for 3 weeks not. Water when needed and use miracle grows house plant fert and another spray for the bugs when needed. The fert is the kind you mix in EVERY time you water. Can you check these pics out and let me know what your thinking? its about 75 degrees in the grow area and about 45% humidity.

Could you please upload these pics onto the Growery servers? Off site links are a bit scary to some of us. If you get some new pics up I'm sure we can get to the bottom of your issue. Thanks!

This looks almost like a small nitrogen deficiency, is it starting from the bottom up?
This just looks like some kind of micro nutrient problem, not sure though, are you using cal mag, or magical?
edit #2, the plants look good to me the yellow in plant 1 is probably just from switching nutes from high n to low n. It happens to me too.

Thanks for fixing the pics. This looks to me to be nute burn, yea its a nute burn. Try picking up a cannabis specific fertilizer and decreasing the frequency of feeding. Should fix it up in a jiffy. Best of luck!

Nute burn would mean too much nutes, the yellowing shows me signs of missing nitrogen which would mean deficient. Guano and Fox farms are good to use. I use guano because its cheap. You are feeding them some kind of bloom booster right? with low n high p?

what is the ferts you are usings NPK ratio? During flowering my plants like to yellow from the bottom up anyways, its kind of normal for them to yellow during flowering.

A defeciency would result in the general yellowing of the bottom leaves, not the scattered blotching with mild necrosis which his plants are displaying. This, coupled with his feeding (of mirical grow which is a harh fertalizer to begin with) at every watering are what lead me to believe it is nute burn. I personally don't grow in soil so I don't have much first hand experince with that type of fertalizer but I have heard great things about the fox farm brand of products. Give it a try and let me know how it works out for you.

It is pretty weird how that plant done that but I pretty much have a plant out of 20 that did the same thing, and it was on the same feeding schedule and all.
That does look almost like an intervienal chlorosis which has a few different causes, lack or lock out of some micro nutes can cause it. And N deficiency also looks a little similar.

From googling necrosis it looks a little like that too.

Supply them with micro nutes and good ferts. Guano is cheap and so is magical and superthrive. Thats all you need really. I cant give you an exact answer on what your problem is il look into my marijuana horticulture book.
After looking plant #2 still looks like its the nitrogen, possibly interveinal chlorosis mixed with a micro nute deficiency. I dont really see how that could be the problem with the fert your using its high in N (but it is miracle grow right? Ive compared guano to miracle grow and the results are kind of amazing). The spots on plant 2 is something totally differnt and looks like a micro nute problem.
