Yield can be hard to guess with so many variables. It all depends on strain, plant size(yours is huge), and conditions. Being outdoors You can really take advantage of lighting with the sun but other variables like weather and location will play a role. Some strains flower faster than others outdoors. If your plant has too long of a flower time it may have trouble finishing which will hurt the yield if it gets too cold outside. I really can't give a for sure answer but if the genetics are made for the climate and it's generally a decent yielder than you should get a pound or 2. This is just more of a guess.
Plants like more sunlight but you can literally still grow them in the shade. They just don't grow as good. From the pics it appears your plants should be getting plenty of light. I still say it's anorexic and not enough N. It still looks good overall and always remember in most cases too little is a lot better than too much. A little burn isn't a necessarily bad thing though. Also make sure you're not over watering. Let the soil dry out a bit before each watering. If you want to make feeding easy next round I suggest trying just easy organic. Just use a higher Nitrogen bat guano in veg then a higher Phosphorus guano in flower. Also use a decent potting soil. this method works great if you are one of those people that tends to be overly worried about burning. You can still add all your supplements but IMO most of them are just snake oils with fancy labels and their packaging destroys our planet.
