Having a heat wave

FTR: Previous to this grow I harvested 4 Gorilla Glue #4 autos from mjseedscanada.com. I harvested about 2 oz per plant of fairly good weed but they did not have the abundance of terpenes from my other crops. I did grow in Promix potting soil mixed with other soil. I had a terrible problem with what seemed as a N deficiency (leaves turned paler green during the grow, even after messing with the nutes and additives. i ALSO APPLIED SUFFICIENT CalMag throughout but couldn't fix the deficiency (?)
