Is this another case of nute burn or is it natural?

The two pics are of the bottom leaves, they aren't the ones that sprout when the plant is just a seedling as they have already been shed. they are starting to go yellow, is this nute burn or is it natural. i know the lower leaves begin to go yellow and die during flowering, but i thought this was a bit early. i recently added more nutes, i think maybe 2 days ago? they are all purpose nutes and they lie just below the soil surface and dissolve slowly as i water the plants. any advice would be appreciated as i will remove some immediately and maybe do a flush.

btw this is just during my first week of flowering so i wasn't sure.

any help would be appreciated

got pics of the whole plant?lower leaves die quick,u shouldnt seat it

that always happened to my plants i didnt know if it was normL or not but it always happened so I just went with it...

ok here's a few of the whole plant. sorry for crapy pics, i only have a camera phone. but as i said before and you will probably see, it is only happening to the lower set that come out after the first initial two as a seedling. it is flowering so i guess this is just normal? btw i know its small for flowering but i ran out of time to continue vegging as i'm on a time limit for this to finish

its normal,nothing wrong,a little streched but u should get some nice buds,make a clone and flower both so u get loose fluffy buds on the mom and compact buds on the clone

o yes a clone isn't a bad idea actually seeing as its getting rather close to maxing out that pot. but wouldn't cloning it at this stage slow it down majorly. right now its covered in preflowers. was stretched cos i was using an mh lamp but it broke as i was going away for the weekend so was in natural sunlight for 3 days and it was cloudy at the time

theres gonna be a few more to fall off yet till the end of flowering after a leaf uses up all it has to offer they just fall right off ...nothing to stress about
