First Grow - Lemon Drizzle

1-2 Weeks till i can finally harvest! We are currently in a heat wave, so temps are pretty high. But i can't do anything against it. Many leafes are yellowing and dying. Hope it's just because the plant is in late Flower and it's normal. Maybe it's missing some nutritions, but we learn from our mistakes! I already have the seeds for the next grow ready! I have Ice Cream Cake, Banana Punch and Laughing Buddha from Barney's Farm. If anybody has any preferences I am open to hear them!
