ak 47 auto deficiency or normal?

Bananatree · Mar 19, 2014

I know that leaves are supposed to turn yellow this late into the grow (9weeks) but it looks a little odd on one of the girls. Its turning yellow around the edges while the rest stays pretty green... instread of a gradual turn from yellow into green the line is pretty clearly defined. dont know how to describe it better... It kinda reminded me of nuteburn but shes not even getting any for like a 4 days now.
Here are some pictures: is this natural yellowing? am I overanalyzing this bud again?

Many strains fan leaves soften to a yellow color as the plant takes food from them, from seed set onwards, many growers of autos over estimate the auto requirements for nutes and over feed ...considerably.

ok thanks but i was actually quite careful with the nutes and never gave more than half strength... and only oldtimer organic bloom too...
So are you saying this is nuteburn or salt buildup in the soil??
