I started growing a week ago and am having problems with some of my plants. I cut off the dead leaves but they were yellow and dried up and turned brownish. I also spoted a little red bug today but i didn't manage to kill him. What should i do??? I use foxfarm grow big and tiger bloom at a 1/4 dosage with ph at 5.8 and it is up to 6.2 now. My temp is a little high at 80 + 70% of the time and 70+ the other 30%. I also used hygrozyme in the mix. I am growing OG, Super OG, Blackberry Kush, Sour Desiel, Banna OG, LSD Kush, and thats it.
