why are my leaves spotting and yellowing??? pictures

My plant is growing outdoors and it started budding about two weeks ago. but now most of the older leaves have small rust colored spots and are yellowing and withering at the tips. I have included these pics if anyone could look and tell me what this could be i would greatly appreciate it. (I havent been checking the ph of the water (i use a reverse osmosis filter and let it sit to become room temp.) i havent given it nutrients apart from some plant food and the organic soil it is potted in. ) thanks again!

Nitrogen defiency i think.

so should i up the levels of the bloodmeal. right now its on a 10 30 10 of bonemeal bloodmeal and glacial rock dust for all the micronuts

You might want to up your micro nutes also. R/O has been stripped of just about everything. Also check ph if possible. Kinda looks like things may be getting a bit on the acidic side.
