Strange yellow patches

I agree with @organoman

I think organoman has nailed this answer for you. Follow the advice.

Burning from way too much nitrogen in its diet. I do not believe it is a deficiency of any sort, just way too much feeding. Try just giving plain water for the next ten days or so, your plant needs to use up what is already there before any new nutrients are added again. I would also suggest half the strength of what you have been giving will be enough once you begin feeding again. Make sure you are watering to run off each time, this ensures nutrient salts don't build up to toxic levels and cause burning, like you are experiencing at the moment. The damaged leaves will not recover, but the new growth should be fine. If you are growing in soil, remember it is plain water/plain water/feed/plain water/plain water/feed..... Hope this helps, Organoman.

Hi. Like Robert's said: Looks like a phosphorus deficiency
