Purps OG, Wi-Fi OG and OG kush in 1 room

I saw that the small plants weren't growing that hard this week so i lowered the secret jardin cosmorrow leds to 15 cm above the plants. it is my first time using these so i still need to find to perfect hanging height for these lights. but no worries since we're not in a rush. next week i'm also gonna start with some extra nutrients.
