mag/cal plant food called MagiCal.
do you have a ppm meter? 200ppm of micros and 6.2-6.6 Ph. the rust spots on the leaves indicate a nutrient uptake problem or irregular watering schedule.
or at worst it could be a root issue.
fox farm veg, grow big right? 6-4-4 or something. thats awesome. the b-52 is a vitamine b1 plus hormone i think. which is also good, better for veg then flower. however i have used superthrive through the whole grow (on most grows) with no problems. the mag/cal go easy on the get. folier maybe...

the rust spots on the leaves idicate an irregular watering cycle too much or too little or both. have you been letting her droop then slamming her with water? because that would be the caase. or it could be a desease in the root zoon.
any strain is a good candidate for SOG. 4 small plants will cover an area of about 1 sqft. under choice conditions, depending on the strain, one could yield a 1/4oz a plant or 1oz a plant. i would suggest a BOG setup https://www.rollitup.org/do-yourself/7523-barrel-green.html
