I didn't know if the yellowing was a lack of nutes or overnuting...

The leaves out of the top of one bud have yellowish brown spots on them. only on 2 of the buds though.

I have been using 10-15-10...but I have some 10-50-10...should I switch???

The small plant on the first pic has only been flowering for 1 1/2 or 2 weeks.
